Error: duplicate listen options for [::]:443 #5550

@iamdubx did you figure this out? I'm having the same issue. |
Same issue... It works for my default site, but not for custom sub domain |
I'm having the same issue. I do have a config to catch multiple domains though.
I get OS: Ubuntu 16.04. Any help? |
Same problem. I ran the command: my original conf file looks like:
according to /var/log/letsencrypt/letsencrypt.log I see certbot is trying to do this:
nginx complains that on the line the actual error message:
a quick google brought up this page from 2010: http://www.serverphorums.com/read.php?5,203912 which suggests that nginx gets confused due to some internal implementation detail. I'm not an nginx expert, but I've tested that the following seems to work:

@ohemorange, do you know if we have an existing issue tracking this? It feels familiar to me but I don't remember whether or not it's something that we've looked into before. |
I have never seen this before. Looks like they fixed the original bug, except when you're using IPv6. And since we just launched IPv6 support, that's why people are hitting this. The solution above will work; I'll see if there's a reason this hasn't been fixed in Nginx for IPv6 yet. |
Actually, you don't even have to do the @joohoi, we probably want to fix this by either removing |
Having the same issue here. Everything was fine for my first domain. The second domain started having these issues. |
It looks like Certbot is unable to detect ipv6only directive completely for some reason. Removing that would fix the issue for most of the users. This can cause some issues with really old Nginx versions, as the behavior of ipv6only and the defaults have changed over the time. |
Apologies for the nasty patch, but this fixed it for me, hopefully there will be a proper fix soon! --- /usr/lib/python3/dist-packages/certbot_nginx/configurator.py.orig 2018-02-14 18:38:30.380863045 +0000

Same issue. Will this be addressed? |
Sorry for the wall of text, but here we go. To shed some light on the issue:
With the recent versions of Nginx this problem does not exist if the
However the default value of
Currently the situation with distribution packaging is that the only distribution that ships with older version of Nginx would be Debian Wheezy (Debian 7), which ships version 1.2.1 of Nginx from the default repositories. If we would remove the The current functionality of Certbot is parsing the complete Nginx configuration, detecting To make decision of the route to fix this issue, we'd need a complete example configuration where Certbot fails in the way described above to be able to improve the detection of an already existing |
Thanks for the patch; that worked for me. FWIW, I'm on Ubuntu 17. |

I comment listen [::]:443 in the subdomain setting, then it works. Is it okay |
also multiple occurences cause problems with `nginx -t`, see: certbot/certbot#5550 (comment)
I just bumped into this issue. Any body trying to make sense of the the different I highly recommend this blog post, until I found this article I was not sure what do with all the different advice I was finding on the web. https://stefanchrist.eu/blog/2015_01_21/Using%20ipv6only%20in%20Nginx.xhtml This quote from the blog post was the light-bulb moment for me.

This error shows up when there are two server blocks listening on the same domain with the same port. |
If you can provide configuration files to reproduce this with an up-to-date version of Certbot, I'd be interested to see them. |

I'm unfortunately not an expert in linux sockets, so I can't form a proper opinion why those options can only be set once, but I'm sure there's a reason.

We don't set it in Certbot. When we create a server block, we copy some directives from the existing default server block, or other template server block, including the listen directive along with its options. This lets Certbot work even if Nginx is behind a proxy or other type of port forwarding. We explicitly delete Ideally, we would do the same for all options that we know can't be duplicated in this way, but leave other options that the user might specifically want all their server blocks to have. To do that, we have to know which options are repeatable, which the documentation does not seem to indicate, and which we only seem to discover through people coming to us on issues like this one. |
Thanks @joohoi |

Edit: Uhhhh, wow, did not realize my version of certbot was so far behind since this was a new machine and I blindly followed the DigitalOcean certbot setup guide here: https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04 Looks like that does not guarantee I get the latest version |

I am having the same issue. It started today after using certbot for a new domain. Now, all my configs don't work and the server won't start now. Has anyone solved this issue? I had no problems until today and have used certbot before without this happening. I have never used ipv6only with my configs; this error happened without having ipv6only added. |
Removing ipv6only=on; fixed the issue! |
My operating system is (include version):
Ubuntu 16.04
I installed Certbot with (certbot-auto, OS package manager, pip, etc):
sudo apt-get install python-certbot-nginx
I ran this command and it produced this output:
nginx: [emerg] duplicate listen options for [::]:443 in /etc/nginx/sites-enabled/example.online:29
Certbot's behavior differed from what I expected because:
It should be no errors
Here is the relevant nginx server block or Apache virtualhost for the domain I am configuring:
