Issue Cannot login to SOGo

[Oldiesmann]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18.0.70 Update #2

I am unable to login to one of my email accounts in SOGo. The same address/password combo works fine if I use Roundcube, but I prefer the SOGo interface. Every other email address works with SOGo as well. There's not much information in the log other than this:

Jun 28 21:27:19 sogod [3342264]: SOGoRootPage Login from '127.0.0.1' for user '[email protected]' might not have worked - password policy: 65535  grace: -1  expire: -1  b>

I tried restarting SOGo and tried changing the password for that address as well. Any suggestions?
