[FAQ] forward 报错 context deadline exceeded #98

IrineSistiana · 2021-03-17T11:25:27Z

forward 报 context deadline exceeded 是因为某个请求发出去了，但过了很长时间(大约5秒)也没收到上游的任何应答。

收不到应答的主要原因：

网络波动 (丢包/长连接被切断等)。

出现零星的警告是正常现象，网络波动不可避免，但日常使用不会有任何感觉，因为客户端/系统都有重试/容错机制。如果希望眼不见心不烦可以将 log level 设为 error。大量警告/日常使用有感觉，说明网络太差，建议使用更可靠的上游。

次要原因:

如果报错都是相同请求类型，可能是上游问题，不能正确处理这类请求。

如果报错都是相同域名，可能是这个域名的托管服务器有问题。

如果确信是 mosdns 的 bug 请开新 issue。

如果单纯是阿里的DNS时常这样何解？我这里(包括其他DNS相关软件)测试有且仅有阿里的DNS会这样。

我的日志info级别是经常出现
2022-02-22T13:15:25.457+0800 warn forward_local upstream/upstream.go:280 truncated udp msg received, retrying tcp
是不是要改成tcp协议

如果很多，是要换 tcp。

这个大量的 context deadline exceeded 正常吗？
"error": "main_sequence: mem_cache: forward_local: context deadline exceeded" 是什么意思？是 forward_local fast_forward请求国内的DNS 超时了吗？

还发现一个问题，经常出现context deadline exceeded之后，所有域名都解析成10.0.0.1，造成上不了网，以前的版本没有这个问题，查看日志也没有什么有用的信息，重启服务后正常。

解决了，clash 的 `dns-hijack` 我配置的是 `any:53`，改为指定为系统 dns 服务器就好了。

我这边也遇到这个情况。
我将 mosdns 设置为 clash 的上游，配置如下

dns:
  enable: true
  use-hosts: true
  listen: 127.0.0.1:6868
  ipv6: false
  default-nameserver:
    - 127.0.0.1:1053
  nameserver:
    - 127.0.0.1:1053
  enhanced-mode: redir-host

一个特别的现象是，当 clash 开启的时候，这时候会有大量的 context deadline exceeded，这时我手动 nslookup 指定通过 mosdns 解析时也会出现无法解析的情况；而关闭 clash 之后，就可以立即解析出结果。因此我猜测可能是并发的问题。

但是加了enable_pipeline=true 和 max_conns=10 也没有变化，配置如下

  - tag: cache
    type: cache
    args:
      size: 10240
      #redis: "redis://127.0.0.1:6379/0"
      lazy_cache_ttl: 86400
      cache_everything: true

  - tag: forward_cloudflare
    type: fast_forward
    args:

ctaoist · 2023-09-09T05:07:00Z

大量出现这种错误，但针对出现这种错误的每个域名，自己用 nslookup 试又能正常返回 dns 记录，就很奇怪，比如：

2023-09-09T12:58:14.041+0800    WARN    seq.r2  upstream error  {"uqid": 679, "qname": "c2.777655.xyz.", "qtype": 1, "qclass": 1, "upstream": "119.6.6.6", "error": "context deadline exceeded"}

但我自己用 nslookup 执行都是ok的：

nslookup c2.777655.xyz 本地 mosdns ip server
# 还是
nslookup c2.777655.xyz upstrem_server

都是ok的

@IrineSistiana 是哪里出了问题吗，不应该啊

出现这种错误好像都是 clash 那边发起的 dns 请求，不清楚是哪一边的问题

一样出现这些日志

如果用OpenClash的话，Default-NameServer添加DNS服务器可以解决

cutbuzz · 2023-12-17T06:16:56Z

hijack

defult-nameserver可以添加127.0.0.1:5335吗？作用是啥？

shaw21003 · 2024-01-13T02:06:10Z

我用passwall + mosdns 也是出现大量这个错误，过一段时间可能几个小时就会科学网络不通，重启服务就又好了，查了好几天，目前把mosdns关了在用。

兄弟，我也是一样。请问解决了吗？

HomeQi · 2024-02-04T21:23:21Z

我也是出现了这种错误，也是passwall2配合mosdns这样，等一个大佬救命。

我都放弃了还是smartdns吧稳定没有这些问题，还找不到解决方法。

把机场节点的地址加入MosDNS的白名单试试，我的就这样解决了。

哎，暂时放弃这个方案了，smartdns可能会慢一点，但是好在设置简单并且可以之前也设置好了去广告了，就不折腾了，谢谢兄弟给的方案，留给其他朋友做个参考哈哈！

我也用smartdns了，感觉速度并不慢，和mosdns差不多吧。一般人用mosdns更简单，自定义又可以很强，但一般人玩不转。我照着官网设置了去广告，都感觉不到效果，电视盒子有广告，浏览器因为有插件没广告，比DNS过滤强大很多，所以不知道smartdns去广告起效了没有。

mumuou · 2024-02-12T03:35:41Z

最近开始用SSRP+也是大量出现这样的错误，过一段时间可能几个小时就会科学网络不通（科学插件显示一切正常），然后导致所有网站都不能访问，就连ping网站和本地运营商的DNS的IP地址都不通，但是SSH连上路由器，路由器本身内外网都能访问，也能ping通，重启服务就又好了，看来不是我的设置问题。

lisuyuan13 · 2024-03-16T06:58:54Z

同样的问题，解决不了

Moebyte · 2024-04-25T14:56:10Z

这个问题还没解决啊，困扰了好几年了

ATFieldBeast · 2024-05-16T04:37:00Z

我也是出现大量的warning后就科学不了了，日志全是远程的dns，mosdns+openclash

yyysuo · 2024-05-17T01:36:07Z

这个问题还没解决啊，困扰了好几年了

mosdns的上游都改成非udp的，比如tls://223.5.5.5，基本上就不会有了，作者其实在上面提过了，包括如果使用clash或者sing-box之类的fakedns作上游，也写成tcp://192.168.1.100:7874这种，再不行log level 改error吧。

stonegr · 2024-05-19T10:20:12Z

我使用doh也出现了这个问题，但是代码中添加这一行，重新编译后已解决

xyl94k · 2024-05-25T10:07:57Z

同样是这个问题啊

求个linux amd64的编译好的二进制，感谢。
