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. [https://crt.sh/?q=example.com](https://crt.sh/?q=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:batcavelounge.eu
I ran this command:sudo certbot --nginx -d [batcavelounge.eu](http://batcavelounge.eu) -d [www.batcavelounge.eu](http://www.batcavelounge.eu)
It produced this output: Could not automatically find a matching server block. Set the `server_name` directive to use the Nginx installer.
My web server is (include version):Nginx 4.2
The operating system my web server runs on is (include version):Linux Ubuntu 14.04 server
My hosting provider, if applicable, is:
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

Its all good 🙂 it found it, but when i tried to disable ssl3 and added a line i get this from your request with nginx -t
:/etc/nginx/sites-enabled$ sudo nginx -t
nginx: [warn] duplicate value “TLSv1” in /etc/nginx/sites-enabled/batcavelounge.eu:100
nginx: [warn] duplicate value “TLSv1.1” in /etc/nginx/sites-enabled/batcavelounge.eu:100
nginx: [warn] duplicate value “TLSv1.2” in /etc/nginx/sites-enabled/batcavelounge.eu:100
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successfu

This is probably because it’s including a file `options-ssl-nginx.conf`, which already declares such a line.

So i should not worry about it ?

Yes, I believe you don’t have to do it because Certbot is already doing it for you.

I’ve hit the same issue twice now, under similar circumstances.
Let me first state that I have done a thing regarding `options-ssl-nginx.conf`- no create or edit. Not having a clue to its function, I have no way of invoking it.
But the circumstance of this arising are eerily similar (I have no hard proof as I was not expecting this to happen).
- have many server names to handle (19 total).
- did an initial certificate with a sub-set of an inital group of 15. Had to set `server_names_hash_bucket_size 512;`
- built up this subset a couple of times.
- later as a couple of other domain DNS entries percolated, tried to add another two, and the error arose.
Any clues to look for?

The error you see is also this one?
> Could not automatically find a matching server block. Set the server\_name directive to use the Nginx installer.

That is correct;
I have little idea how to set server\_name directive. I don’t understand why it initially works, Certbot then generates its own block
`server_name [...].net; # managed by Certbot` then complains…

Could you show the output of `nginx -T` as suggested by @_az above?
Edit: Also, what version of Certbot are you running?

yes, file enclosed[nginxT.txt](https://global.discourse-cdn.com/letsencrypt/original/3X/1/a/1ad881074591a4a0309260a3111bff858e390b12.txt) (10.7 KB)
.
I am not certain how to extract that version. a `sudo certbot -v` gave unexpected result, but had interesting snippet
certbot==0.21.1
Basically this was installed today.

Thanks, and could you also provide a log from `/var/log/letsencrypt` corresponding to a time when the error occurred?
