--But i have only 443 running.
apachectl -t -D DUMP_VHOSTS
VirtualHost configuration:
*:443 is a NameVirtualHost
default server mta-sts. (/etc/apache2/sites-enabled/mta-sts-ssl.conf:3)
port 443 namevhost mta-sts. (/etc/apache2/sites-enabled/mta-sts-ssl.conf:3)
port 443 namevhost webalizer.caloro.ch (/etc/apache2/sites-enabled/webalizer-ssl.conf:3)
port 443 namevhost www.caloro.ch (/etc/apache2/sites-enabled/wordpress-ssl.conf:3)

Please how can i update this Cerrt!!
Thanks

Ok i need only to enable the 000-default.conf, than certbot renew will run without problem.

But if running only with port 443, why the 80 i need? this only for recertify?
Thanks for possible help!

Yes, if using HTTP challenges (which is the typical case it seems), you need to keep port 80 open.

Port 80 only needs to do that one thing: Complete the LE challenge.
And it can do it in several secure ways:

  1. redirect ALL connections to HTTPS
  2. handle the acme-challenge requests in HTTP and redirect ALL other connections to HTTPS
  3. handle the acme-challenge requests in HTTP and return 404 for all other requests
  4. use a completely different web server service to provide this HTTP function only
  5. use a completely separate server to provide this dedicated web server service
  6. use a reverse proxy to reach the real (HTTPS) web server (only for acme-challenge requests)

I could go on, but I think you should have a good idea of options that can be run all the time and yet be secure enough to let you sleep at night. :slight_smile:
