Server has been running for a few years - issue came up with /boot being filled up & services not working correctly.
Went through the removal of older kernels to allow me to update
Ran the bash setup command to upgrade to latest which is running
I can get to /admin /cloud & /mail pages
/admin & /cloud logs in perfectly
/mail refuses to login
Mail users are unable to IMAPs or SMTP through the server.
RoundCube error.log shows the following
Could not connect to ssl://localhost:993: Connection timed out in /usr/local/lib/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 200 (POST /mail/?_task=login&_action=login)
Have confirmed that 993 is LISTENING on the server
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN
Have done apt-get update/upgrade & re-ran the setup commands
All completes perfectly but the connection is unable to complete.
Not sure what else to do ?
