Everything was working and suddenly thunderbird shows the message: Can’t connect to server
I tried to log into Rainloop and also the same message

I went to see the status and the problem follows.

systemctl status cpecs.service

Can someone help me? The server is already in production

do you have an idea or help?
I have been suffering for days.
we managed to see that after enabling EMAIL POLICY SERVER, port 1089 does not open and remains closed.

please help.
