This problem has been affecting me since I installed roundcube, I can't get Gmail's IMAP settings to work with it.
The SMTP settings work fine:
Trying to send email...
SMTP send: OK
But when I try to use Gmail's IMAP settings, I get the following error:
Connecting to ssl://imap.gmail.com...
IMAP connect: NOT OK(Login failed for **** from 18.104.22.168. Could not connect to ssl://imap.gmail.com:993: Connection timed out)
I've tried multiple things, including contacting my server to see if the port was blocked (it wasn't), but nothing is working.
I can't figure out the problem and there are no posts on the forum with a solution.
