Do you want to request a feature or report a bug?
maybe

What is the current behavior?
PS. I tried to solve this by searching here and by Google, but not one approach solved it. I also uninstalled, cleaned up caches, rebooted mac. Clean DNS, Flush everything I could. I did everything I know.

After install zsh keeps saying "There appears to be trouble with your network connection. Retrying..."

Got the same behaviour when I try to add a new module and the yarn.lock file exists.
I solve it by removing the yarn.lock file.
Then the yarn.lock file is being recreated (which is what I want)
And then I face again the same issue when I add a new module (yarn add ..) , remove yarn.lock and it works again.

[HarshulSharma000]

Getting the same issue on
OS: Windows 10
Node: 9.4.0
Yarn: 1.4.0
npm: 4.6.1
Watchman: 4.9.1
Xcode: N/A
Android Studio: Version 3.0.0.0 AI-171.4443003
Packages are resolved but fetching is not happening, no lockfile generated, tried to edit network timeout also nothing happened. tried to move to earlier versions like 0.24.6 problem still persists.

[torifat]

@rooozox is it possible for you share your package.json and yarn.lock file?

[rooozox]

@torifat Sorry, I'm not able to replicate it anymore. I tried several times but now it works well. If it happens again I'll post back detailed infos.

[jarvis18]

I am having the same issue on Ubuntu 16.04

[KrisSiegel]

Interesting; on Ubuntu for Windows I've hard Yarn do this multiple times. npm install works fine and all other network connectivity works fine. To workaround I just ctrl + c and run yarn again. Almost always works.

Not sure what's going on and I haven't been able to create a small, reproducible project to share in an issue it's just something that happens sorta regularly for me with various projects.

[MichelDiz]

I trying some "voodoos":

• Delete any "*.lock" and rm node_modules. Or rm -rf node_modules/

• Clean a flush all connections things like DNS, caches and so on.

• Terminal commands:

• set http_proxy=

• set https_proxy=

• yarn config delete proxy

• npm config rm https-proxy

• npm config rm proxy

• npm config set registry "http://registry.npmjs.org" or npm config set registry "https://registry.npmjs.org"

• Restart your terminal and Try.

• Use : yarn add mypckge --network-timeout 100000 or yarn --network-timeout 100000
  but first try just yarn

• Restart your terminal and Try yarn again and/or with --network-timeout.

For me is working for now. I'll see how will be over time.

[andrewnaeve]

I am also experiencing this. Internet pulling down 70Mbps,

Timeout increase did not resolve, tried nuking docker containers, removing package.lock etc.

However, I got around this by tethering my phones LTE. wtf?

[Hinaser]

I also have the same issue.

error An unexpected error occurred: "https://registry.yarnpkg.com/nyc/-/nyc-11.7.3.tgz: ESOCKETTIMEDOUT".

Trying to isolate the issue
There are 3 suspects.

• My windows PC's hardware (Network adapter maybe)
• Client OS/Software issue
• Remote npm server

I tried to issue the same yarn command on Virtual Ubuntu 16.04 running on my Windows PC by Hyper-V.
The result was successful. The virtual machine had no problem to install the new npm package.

At this time, I strongly suspect that the problem is in Windows 10 OS or yarn execution binary.

Looking deeper

I ran WireShark to monitor TCP packet between registry.yarnpkg.com and my windows PC,
and I found very interesting packets which might be the root cause.

Everytime the message There appears to be trouble with your network connection. Retrying...
is output on console, there is a RST packet sent from my PC to npm server.
You know, RST packet is to forcibly close TCP connection.
But it is sent from client PC.
I feel strange about this.

Next, I wondered what causes RST packet sent from my PC.
I found that every time before RST packet is sent, there are packets indicating TCP ZeroWindow, meaning data receiving entity (in this case it is my client PC) tells to a sender to stop sending packet until the receiver allow to do it.

After sender receives packets indicating TCP ZeroWindow, client must send TCP Window Update to server in order to resume TCP communication.

But I couldn't find those TCP Window Update packet sent from my client PC.
The npm server kept waiting to be allowed to send data but my client PC didn't tell to do so.
Then it is timed out and RST packet was sent from my PC.

Apparently, the root cause is not to send TCP Window Update packet to resume communication from client.
As I haven't had problem downloading large files from internet, I suspect the issue is in network code in node binary compiled for Windows.

[daisennomori]

Same issue here
--network-timeout 1000000 worked for me.

OS: Windows 10 1709 , WSL: Ubuntu 18
Node: 10.1.0
Yarn: 1.6.0

[Schlaefer]

OS: macOS 10.13.4
Node: 10.1.0
Yarn: 1.6.0

Same issue here. Connection timeouts and can't find packages on npm registry. Installing the same package via npm works fine.

Looking into the traffic as @Hinaser did I also see RST packages before the failure. The network is using a AVM FRITZ!Box 3272 router to connect to the Internet. Taking it out (connecting directly to the modem or using a different router) "fixes" the issues. Putting it back in and the errors are back.

edit: Router reset fixed it this time.

Increasing the timeout also worked for me but not really a solution.

[raghudevan]

Strange thing is I'm getting this error only when I do a yarn install from a docker container (node:carbon). If I run yarn install from my development terminal, all is fine 🤔

edit: it works on my local machine because of the yarn cache!

[rodrigobdz]

There appears to be some trouble with the npm servers right now.

[hopewise]

The same issue here..

[Glideh]

Interesting thing is from an other physical location (also different host both in the same country though) with the same docker image I don't get the error.
So maybe the npm servers have significant response time differences depending on the locations.

[NguyenHoangMinhkkkk]

suddenly i did it success. try again guys

[felix-weizman-deel]

Still having issues as well.

This time all systems are operational.

[knoxcard]

@MichelDiz - thanks a mil

[backspaces]

I just ran into this as well. Tried removing yarn's lockfile and node_modules/ Using npm install works fine. Also fails on CI which uses yarn for install and build.

Anyone have a hint on how to proceed? I could do a fresh clone etc but this seems really odd.

[sergey-shpak]

after about 2 hours and trying all the solutions, finally this worked for me:
npm config set registry "http://registry.npmjs.org"
and then:
yarn config set registry "http://registry.npmjs.org"

[xccjk]

The same problem exists on my machine.
OS: macOS 10.14.6
Node: 14.15.0
NPM: 6.14.8
Yarn: 1.22.10

In some networks, the initialization project is very slow, and the network reason is always prompted, but the installation is successful, and it took about 10 minutes

After turning on the circumvention network, it is still as smooth as before

Do you know the reason？

[Hazmi35]

I have the same problem, but only when I'm building multi-platform Docker images with buildx, when I first received this problem, I think it's only a network issue from my home network, but it's actually not, it's also affecting my docker/build-push-action in https://github.com/Hazmi35/jukebox too, strangely it's not affecting the AMD64 platform as you can see in https://github.com/Hazmi35/jukebox/runs/1430274704?check_suite_focus=false, AMD64 only takes 74.1 seconds, which itself is quite slow, but ARM platforms (ARM64, ARMv7, and ARMv6) can take up to 1136.06 seconds. Any tips? I've using network-timeout 600000 to prevent the build from failing. But now it's very slow

[merceyz]

Closing as fixed in v2 where the timeout logic is less susceptible to this sort of issue

https://yarnpkg.com/getting-started/migration

[aprilmintacpineda]

I'm having the same problem when running yarn add or yarn global add on Github actions. It's intermittent. Sometimes it recovers, sometimes it fails.

[sibelius]

@Hazmi35 did you figure it out how to improve yarn install times when building ARM?

[sibelius]

related issue nodejs/docker-node#1335

[Hazmi35]

@Hazmi35 did you figure it out how to improve yarn install times when building ARM?

@sibelius Sadly no, I moved to npm when I tried Yarn 2 on that project and it seems to be incompatible. Although, before that, I don't see any issues about the slow download other than the compile-time for native modules is slow in emulated build, and it's also happening with npm.

[ivolucien]

Yet another way this issue can occur, if you have a split dns setup with a vpn, the default dns server needs to resolve the npm registry. For my setup this worked:

sudo resolvectl default-route [your-vpn-device-name] true && sudo resolvectl default-route [your-internet-device-name] false

[sunny-to]

I was running into this in a Docker container. I think it was actually a disk space issue and not a networking issue, as deleting all my unused Docker images fixed the issue for me.

[ranjithrd]

If someone is still facing this issue with scoped packages (@types/react for example), please refer to #8797
It can be fixed by using node version v17.7.1

[odahcam]

After trying everything I could, today the problem just stopped happening. 😵‍💫

[natesdot]

I have been troubleshooting this issue myself for several hours now, and my situation is different from all others that I have seen but the same error persists. Wondering if anyone could shed some light on the situation.

I get this error only running inside of docker, if I run the same commands on the host it works fine(100% of the time). The connections are very fast, installing packages takes just a few seconds in both cases. So there is no timeout situation(but have tried messing with that option). Running wget/curl against the "failed" urls results in success 100% of the time.

However yarn continues to report sporadic "trouble" when running inside of docker.
I made a small breakthrough a short time ago, found that running docker with --network host allows the commands to run without errors. So I am assuming it has something to do with the docker iptables rules in my case? I'm no iptables expert or even at this point I wouldn't even consider myself a novice it's probably been 10+ years since I last touched iptables. The problem happens on all hosts, using the default docker setup/rules. So I can't imagine it would be related to iptables, but what else could it be if --network host resolves the issue for me? I don't know..

I have been troubleshooting this issue myself for several hours now, and my situation is different from all others that I have seen but the same error persists. Wondering if anyone could shed some light on the situation.

Mostly pure luck I suppose, but I managed to fix my issue by setting these sysctl flags

• net.core.wmem_max=12582912 (default was 212992)
• net.core.rmem_max=12582912 (default was 212992)

I never thought I'd need to adjust a kernel setting like this for an otherwise completely idle system running just one container and this yarn program accessing a few urls. Can't say I've touched these parameters much at all in my 26ish years of using Linux.

[Juanc1to]

After poking at many of the proxy, cache, and timeout settings that others have suggested, I also rebooted my router and that immediately fixed the problem. It is certainly curious to me that the router can get into a state where these yarn network requests time out, but all other "normal" internet traffic functions properly. I would be very interested in learning more about what might cause the router to get into such a state!

[IshanKute]

I am also experiencing this. Internet pulling down 70Mbps,

Timeout increase did not resolve, tried nuking docker containers, removing package.lock etc.

However, I got around this by tethering my phones LTE. wtf?

Thank you so much. Weird but this is the only thing that worked for me.

[RickGoGo]

yarn install --pure-lockfile --proxy http://<proxy-address>:<port> finally worked for me after tried lots of solutions. (I'm using VPN)

I realized yarn command would not use your system proxy automatically so we need specify by yourself.

In my case, I could successfully download the package by using the resolved URL in yarn.lock file but failed to perfrom installation by yarn install in the terminal.

That make sense to specify the proxy address when a proxy needed to access the resolved URL in your region.

isso resolveu meu problema, eu te amo seu gringo lindooo <3 <3

[jahammo2]

For anyone still running into this issue, the fix for me was to connect to a different WiFi connection.

None of the other tricks (adding --timeout, yarn cache clean, npm config rm proxy, etc) worked but changing my WiFi connection did 🤷‍♂️ .

[CalebFenton]

My problem was that my docker daemon didn't have ipv6 tables enabled. I had ipv6 enabled but not the tables. https://docs.docker.com/config/daemon/ipv6/

I diagnosed this by running the docker container's /bin/ash and checking network stuff. I could ping my router, ping my DNS, and resolve domains to IPs, but I couldn't ping google because that went to an ipv6 address. After fixing the daemon config and restarting the service, everything worked fine.

[callmebar]

In my case, I've gotten ETIMEDOUT immediately after yarn install no matter how huge was --network-timeout. I was monitoring packets through WireShark and noticed that in TCP handshake my side sends RST after getting SYN,ACK from yarnpkg server. Digging deeper, I found the reason.

node:net has a parameter autoSelectFamilyAttemptTimeoutDefault be default it is 250ms, that is not enough for my slow internet connection. This parameter at the current version if node (v21.7.1) can not be changed by NODE_OPTIONS, only from code, so all the libraries that use node.net must adjust this parameter, but they do not.

So it is not really yarn problem, but it can be fixed on the yarn level by, for example, running net.setDefaultAutoSelectFamilyAttemptTimeout(networkTimeout) in utils/request_manager:setOptions.

However, since I can't fix all libraries that ignore this parameter, I manually patched this line in node and built it from source.
