Issue Webmail Stopped Working After Plesk Update

A

apaunovski

Basic Pleskian
So, the other day I saw that PLESK has updated itself, and now webmail (RoundCube) isn't working anymore.

When I try to access webmail.domain.com it throws 403 error at me.

I am using the LiteSpeed extension if this makes any difference. Sites work fine. Webmail does not.

I am not even sure what logs to look at so I can understand better where the error is coming from.

Please help!
 
Code: 
tail -fn0 /var/log/plesk/panel.log
For Plesk Onyx 17.5, install the latest Plesk micro-updates .

For Plesk Onyx 17.0 and earlier Plesk versions, consider upgrading to the latest Plesk version .

If the upgrade is not acceptable, apply a workaround:

via GUI:

Go to Plesk > Tools & Settings > Website Preview, select Default Quick Preview and click OK.

via CLI:

1. Login to Plesk via SSH
2. Identify server IP addresses:
Code: 
# ip a
Code: 
# echo "server_ip" >> /etc/sw-cp-server/conf.d/trusted_ips.inc
 
Code: 
tail -fn0 /var/log/plesk/panel.log

Does not output anything.

I ran
Code: 
plesk installer update
to install all PLESK updates and it went smoothly without any problems.

Still, the situation with Roundcube didn't change.

Code: 
echo "MY.SERV.ER.IP" >> /etc/sw-cp-server/conf.d/trusted_ips.inc
didn't do anything and the issue still persists.
 
Please change webmail to horde, than change back to roundcube, my this will fix your problem.

I would like to help but without an error_log it will be difficult.
 
Code:

Thank you, however, this is not the error I am getting, and besides, if I switch to HORDE, I keep getting the same error when I access webmail.domain.com.
 
Symptoms
When trying to send e-mail following error appears:
Click to expand...

I am not trying to send email. The very second I try to access webmail.paunovsky.com (this is my domain, however it's valid for ALL DOMAINS on the server) I get an error 403!

Apache's ERROR LOG looks like this:

The problem still persists.
 
OK, so...

Switching back and forth between LiteSpeed and Apache showed that the problem happens only with LiteSpeed.

Just wanted to add that after upgrading LiteSpeed to v5.3, the error message changed to ERROR 500...
