Having Trouble installing certs

Help
1

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: captainnemo.icu

I ran this command: certbot install --cert-name captainnemo.icu

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Deploying certificate
Could not install certificate
Could not automatically find a matching server block for captainnemo.icu. Set the `server_name` directive to use the Nginx installer.

My web server is (include version): nginx version: nginx/1.14.2

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: Debian 10

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.28.0

I did go to /etc/nginx/sites-available/default and added my url to server_name. I then ran sudo systemctl reload nginx and certbot install --cert-name captainnemo.icu but got the same error.

Hi @johnblood, and welcome to the LE community forum :slight_smile:

Please show the outputs of:
grep -Eri server_name /etc/nginx

Thanks, @rg305

grep -Eri server_name /etc/nginx =

/etc/nginx/fastcgi.conf:fastcgi_param  SERVER_NAME        $server_name;
/etc/nginx/scgi_params:scgi_param  SERVER_NAME        $server_name;
/etc/nginx/sites-available/default:     server_name www.captainnemo.icu captainnemo.icu_;
/etc/nginx/sites-available/default:#    server_name example.com;
/etc/nginx/sites-available/reverse-proxy.conf:        server_name localhost;
/etc/nginx/fastcgi_params:fastcgi_param  SERVER_NAME        $server_name;
/etc/nginx/nginx.conf:  # server_names_hash_bucket_size 64;

/sites-available/ is not the same as /sites-enabled/.

So, do I need to add my url to /sites-enabled/ ? I read through a bunch of stuff prior to creating this threat and got confused.

Yes. Only the configuration files from that directory are included, not those from the "available" directory.

Do I need to reset my changes in /sites-available/?

No, that underscore was incorrect anyway. I believe nginx can make use of the underscore in server_name, but AFAIK only as a "separate" entity (i.e.: not "stuck" to another hostname). It does not have any use in your situation I believe.

So, do I need to edit /etc/nginx/sites-enabled/reverse-proxy.conf ?

Is reverse-proxy.conf even in /sites-enabled/? Because from your previous grep for server_name, it was only in /sites-available/.

In any case, the way some nginx installations work are that all available configuration files are in /sites-enabled/ and if the sysop wants to enable one of those, the configuration files from /sites-available/ are symlinked into /sites-enabled/.

I have no idea what reverse-proxy.conf does, so I also have no idea if it should be enabled or not.
