Fail to expend to one subdomain

[gfelot]

Hi there,

I got a server powered by Nginx. I setup my main web site and 2 subdomains.
Everything works well.

I added a new webservice where I want to put on an other sub.

If I try :
./letsencrypt-auto certonly -a webroot --webroot-path=/var/www/html -d gfelot.xyz -d www.gfelot.xyz -d plex.gfelot.xyz -d dl.gfelot.xyz -d kibana.gfelot.xyz

I got :

IMPORTANT NOTES:

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.

I dunno what’s wrong because I already try to renew my certificat and it was working well.

Any Idea ?

Your servers aren’t reachable from the internet:

osiris@server ~ $ telnet kibana.gfelot.xyz 80

Sorry I was playing with my server block to try to resolve the issue.
I change that right now. My bad !
