SUMMARY
IMAP mail account, address book and calendars can't go online.

STEPS TO REPRODUCE
1. Set up a new IMAP account in kmail, a DAV address book in Kontact and a DAV calendar in KOrganizer
2. Folders/DAV are synced, but no mails/contacts/calendar data, as account goes immediatly offline
3. Telling the account to go online has no effect. All other apps, also thunderbird, are online and retrieve/send without a problem to the same server over the  same connection.

OBSERVED RESULT
Mails/contacts/calendars can't be synced, no matter what.

EXPECTED RESULT
Mails/contacts/calendars should be synced, account should be online checking for updated data.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: OpenSuse Tumbleweed
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.9.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION
I use nordvpn for the interrnet connection, but as I said, all this works over the same connection with thunderbird. As all the parts of Kontact are affected, could akonadi be the problem?
