I did, a couple of times, it even went to Maximum daily limits by Letsencrypt.
It connects my unchecking / OFF ( Always use a secure connection SSL when retrieving mail.)
What else should i try?
I copy the SSL from the Website like this.
To mail server
I uninstalled Mailserver 4 times and installed Round Cube a few times.
Checked Firewall, all is good.
Restarted the server a few times.
Checked the Logs, nothing unusual,
Removed ports 995, 110 etc... and enabled them again.
I think, the issue is on the SSL, ill try removing them manually, and generating one on a different site.
Server info.
