RoundCube; what are common errors?

[AndyHestia]

Hi,

my RoundCube mailbox is not working.
It says: An internal error has occured. Your request cannot be processed at this time.

On TCP connect, check port : Check host - online website monitoring I performed a check;
mydomain.com:143 and mydomain.com:993

Both resulted in Connection Timed out.

So, according to https://support.theory7.net/hc/en-us/articles/14486653833618-Roundcube-webmail-most-common-errors-solutions ,
my e-mail / IMAP server is not working properly.

Has anyone endured the same behaviour?

What can I do about it?

Thanks

It’s a bug, to fix it execute these commands as root:

chown -R hestiamail:www-data /etc/roundcube/
find /etc/roundcube/ -type f -iname "*php" -exec chmod 640 {} \;
chown -R hestiamail:www-data /var/lib/roundcube/
chown -R hestiamail:www-data /var/log/roundcube/

That’s strange but you should check whether dovecot is up and running, it is listening on the right ports and you have no rules blocking those ports.

systemctl status dovecot --no-pager -l
lsof -Pn +c0 -i:143,993 -sTCP:LISTEN
iptables -S

Thanks for your help.
Yes, the commands resolved the problem.

I checked dovecot now, and it seems it is up and running.

However, still get those “Connection Timed out” results over at TCP connect, check port : Check host - online website monitoring

All looks ok on your server side, are you redirecting the right ports from your router/or the firewall of your hosting provider?

If you share your domain or ip, I could test it from my side. If you don’t want to share it publicly you can send me a private message.

Thanks, I resolved the issue.

Had to take care of the ports, as you said
