Certbot can't contact my server through https (443), but the port is open

I do have the port 443 open (checked with many tools, like this one: http://ping.eu/port-chk/)
Tshark shows 443 traffic while the command is being run, but no 80 traffic
I have added this port to the ports.conf in the apache2 folder

My domain is: rebane2001.com

I ran this command: certbot --apache

It produced this output: Failed authorization procedure. www.rebane2001.com (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to for TLS-SNI-01 challenge, rebane2001.com (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to for TLS-SNI-01 challenge

My operating system is (include version): Raspbian 8 (Debian Jessie)

My web server is (include version): Apache 2.4.10

My hosting provider, if applicable, is: Myself

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

Well, your Apache is serving normal HTTP through port 443… This should be HTTPS. I’m not sure Boulder generates the “could not connect” error when the TLS connection fails, but it sure looks like it:

Thanks, I suck at networking, so could you tell me a bit more about how I could solve it? :slight_smile:

Is mod_ssl enabled?

As far as I know, it should be

You might want to triple-check that.

As I said, I suck at such stuff, so I am not 100% sure, but my guess is that something is wrong with some configuration files, rather than mod_ssl, but I’ll check once more

I was able to solve it.
To anybody who has the same problem, add “ServerName localhost” to your apache2.conf and remember that your Vhost is in /etc/apache2/sites-available/ :wink:
Thanks to Osiris aswell

Hm, glad you solved the problem! I’m not sure I understand how and why, but I’m happy for you :stuck_out_tongue:
