Cannot find a VirtualHost matching domain mydomain.cz

[Pooik]

Hi,

I’m getting error Cannot find a VirtualHost matching domain mydomain.cz when trying to generate certificate with certbot:

pooik@server:~$ sudo certbot --nginx certonly

My nginx.conf looks like this:

  include       mime.types;
  default_type  application/octet-stream;

  sendfile        on;

  server {
    listen  80;
    listen 443 ssl;
    server_name mydomain.cz www.mydomain.cz;

    }
  }

  server {
    listen  80;
    listen 443 ssl;
    server_name mydomain2.cz www.mydomain2.cz;

    ssl_certificate      nginx-selfsigned.crt;

Any ideas?

Hi @Pooik,

Can you tell us what version of Certbot you’re running? Certbot’s nginx support has improved a lot over time, and so it’s possible that this failure is associated with using an older version.

@erica, have you seen this kind of error with “nginx restart failed” before, by any chance?

[erica]

I’m definitely interested in seeing what version of Certbot this is, because if there’s a problem with the config files (which leads to the “failed to restart” error), it shouldn’t be getting to “please enter in your domain names” (which it shouldn’t be doing anyway, since there are domain names in there).

Hi,

I’m running version 0.17.0. I was installing it yesterday, using this: https://certbot.eff.org/#ubuntuxenial-nginx

Thanks

Hi,

any new thoughts?

Thanks

[Pooik]

Isn’t the problem that I’m not using sites-available? I’m having all in nginx.config?

[schoen]

Hi @Poolk,

I think your guess is plausible.

You might not be able to get a reply from @erica about this right away because this is a holiday weekend in the United States, and so she won’t be back at work until September 5.

[erica]

No, sites-available-based configs should be treated the same as including it all in a single config file.

Is nginx.conf located in /etc/nginx/? If not, you can use the --nginx-server-root flag to set it to the directory containing nginx.conf.

[Pooik]

Ok, my nginx intallation seemed to be completely uncommon, so I reinstalled whole VPS according to this tutorial https://gorails.com/deploy/ubuntu/16.04 and now the certification ran correctly.

So thank you

[erica]

Glad you got it working!
