Struggling to get AutoSSL with a valid certificate

Hello All,

A little rusty understand all the SSL side of this, but I’d very much like to get it up and running.

I’m running a RC server on Ubuntu 16.04 with the snaps method in the tutorial. I’ve got SSL working in Caddy by issuing the ‘tls self_signed’ line to my config. We all connect on https://example.uk.to:2015 as that’s the port Caddy seems to have issued us.

To try and get rid of the unrecognised certificate error every 7 days, is there an idiot-proof guide I can follow to get a valid certificate installed and keep the port as 2015 to save re-configuring everyones client? I can’t seem to see anything (or I’m just extremely stupid)

Thank you in advance!
