Cannot Login after following tutorial to change url and setup auto ssl using snaps

Community Support
1

i have followed the snaps documentation to change url for my rocket.chat server and also set up auto ssl.

After i setup the original install, the url in /etc/hosts was

127.0.0.1 localhost
127.0.1.1 host.fqdn (my hostname.domain.com)

When i tried to setup Auto SSL it did not work, and i think the reason was because of the etc/hosts file above. So I changed the /etc/hosts to the following

127.0.0.1 localhost
host.fqdn

I was able to setup Snaps AutoSLL successfully. However, when i go to browser (or desktop app)
and enter my https://host.domain.com:3000 i cannot get to the server …i get

# This site can’t be reached

host.fqdn refused to connect.

I have changed my /etc/hosts file to read the following

127.0.0.1 localhost
127.0.1.1 host.fqdn
host.fqdn

however i still get the same error in browser.

Finally, I can resolved in dns lookups. For example if in command shell i type

dig host.fqdn

i get the following (edited)

root@host.:~# dig host.fqdn

I have also found the following when checking rocket.chat-server status…

ok i have narrowed the problem down (i think to rocketchat-caddy).

If i shut down caddy, i can then restart rocketchat-server.

As soon as i enable caddy, rocketchat-server fails

of course, the second i attempt to login with web browser, it the rocketchat-server immediately enters a failed state again. (with either http or https)
