Summary of the issue you are facing:
I enabled the Caddy community container in NC AIO with the hope of being able to host extra services on the same server as my Nexcloud install. The docs said it was self configuring for Nextcloud and the auto supported services via the env variables. However after restarting all the containers I was left not being able to connect to Nextcloud, which was working fine before. I guessed that the Caddy container didn’t auto config in the way I thought it was going to, so I disabled it. But this hasn’t resolved my problem, I’m still unable to connect to NC and get a SSL_ERROR_INTERNAL_ERROR_ALERT in the browser when I try. I still have a AIO admin tab open which works, but new connections don’t. So I think the certificates have been messed up by enabling the not properly configured Caddy container.
I have started everything including the server and no change. How can I get access back?
