My home connection blocks port 80 and 443. I’ve set the apache server to listen on 81, but I don’t know how to make letsencrypt listen on a port other than 443.
I ran this command: sudo letsencrypt --apache
It produced this output:
Failed authorization procedure. somedomain.net (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to xxx.xxx.xxx.xxx:443 for TLS-SNI-01 challenge
My domain is: a domain I’d rather not share
My operating system is (include version): Ubuntu Server 16.04
My web server is (include version):
Server version: Apache/2.4.18 (Ubuntu)
Server built: 2016-04-15T18:00:57
My hosting provider, if applicable, is: Home Internet connection
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
Is there a way around this? Also, the IP address is dynamic so I’m using a Dynamic DNS service provided by Dynu to keep DNS up to date. Any tips in the right direction greatly appreciated!
