My domain is: avima.pl
I ran this command: ./certbot renew
It produced this output: 2017-04-16 11:40:23,106:WARNING:certbot.renewal:Attempting to renew cert from /etc/letsencrypt/renewal/avima.pl.conf produced an unexpected error: Failed authorization procedure. avima.pl (tls-sni-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Incorrect validation certificate for tls-sni-01 challenge. Requested db0f72c1efa81c80b779f47cfc964c19.b8db56e8b9ded800119b6257ad0d65a6.acme.invalid from 18.104.22.168:443. Received 2 certificate(s), first certificate had names “192.168.1.1”. Skipping.
My operating system is (include version): Debian
My web server is (include version): lighttpd/nginx
My hosting provider, if applicable, is: selfhosted
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
Essentially, i’m using a docker-mailserver (https://github.com/tomav/docker-mailserver) and configured let’s encrypt certificate to use with it, as described on their wiki. I believe i used a stock nginx config to get the cert in the first place. My regular webserver is lighttpd. Certificate expired not so long ago and ever since i can’t renew it. I have no idea where 192.168.1.1 came from as well since my internal network IPs are and always have been 192.168.0.x.
