I have a simple personal website
yohannparis.com that I want to make HTTPS.
I setup my Nginx server block following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-server-blocks-virtual-hosts-on-ubuntu-16-04
And I followed this tutorial to install Let’s Encrypt on my server block: https://www.digitalocean.com/community/tutorials/how-to-set-up-let-s-encrypt-with-nginx-server-blocks-on-ubuntu-16-04
Everything worked like a charm, up to Step 4 where the following command:
sudo certbot --nginx -d yohannparis.com -d www.yohannparis.com
Saving debug log to /var/log/letsencrypt/letsencrypt.log Could not open file: /etc/nginx/sites-enabled/yohannparis.com Plugins selected: Authenticator nginx, Installer nginx Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org Obtaining a new certificate Performing the following challenges: tls-sni-01 challenge for yohannparis.com tls-sni-01 challenge for www.yohannparis.com Cleaning up challenges Could not open file: /etc/nginx/sites-enabled/yohannparis.com Cannot find a VirtualHost matching domain yohannparis.com. In order for Certbot to correctly perform the challenge please add a corresponding server_name directive to your nginx configuration: https://nginx.org/en/docs/http/server_names.html
I checked the permissions on my server block file in
/etc/nginx/ but it all look good:
. ├── [drwxr-xr-x] conf.d [...] ├── [drwxr-xr-x] sites-available │ ├── [-rw-r--r--] default │ └── [-rw-r--r--] yohannparis.com ├── [drwxr-xr-x] sites-enabled │ └── [lrwxrwxrwx] yohannparis.com -> sites-available/yohannparis.com [...]
I tried to access the log on
/var/log/letsencrypt, but it wasn’t helpful:

I changed my server block file permissions to
777, but to no effect!
Where can I found a solution to this issue?
Thank you for your help. Yohann Paris

I also had this problem but this ended up working for me:
It has to do with broken symlinks in /sites-enabled. A symlink may break for different reasons, in this case, nginx can still follow the link, but certbot cannot. Why? I don’t know tbh.
To fix, I simply removed the symlink and created a new one.
If you list the directory you can typically spot a broken symlink with red text and a black background, and a working symlink with blue text:

Hope it’s this simple for you.
