Description Thiago Macieira 2020-07-15 17:35:20 UTC 
SUMMARY
In Akonadiconsole, the IMAP agent may display "Connection Established" but have no active IP socket open.

STEPS TO REPRODUCE
1. Disable Qt bearer plugins: chmod 0 /usr/lib64/qt5/plugins/bearer
2. Restart IMAP agent

OBSERVED RESULT
"Connection Established" is shown, never changes, but there's no outgoing socket open.

EXPECTED RESULT
Either there's an active socket connection or the state is something different.

SOFTWARE/OS VERSIONS
openSUSE Tumbleweed 20200701
Qt: 5.15.0
KDE Frameworks: 5.71.0
kf5-config: 1.0

As you can see, there's no "inet" file descriptor.
Comment 1 Arek Guzinski 2020-11-29 19:58:17 UTC 
Same problem here with 5.15.3 on KDE neon (20.04 based)

in akonadiconsole:
Akonadi Server Self-Test shows no errors.
IMAP agent:
Status: Offline, Idle
Status Message: Connection established

lsof -n -p `pgrep -f akonadi_imap_resource_1` | grep -v 'mem'
shows no IP file descriptors (this is on my main computer - it does show them on my laptop, where akonadi is working fine)

But: bearer plugins are enabled (or am i missing one?)
# ls -la /usr/lib/x86_64-linux-gnu/qt5/plugins/bearer
total 612
drwxr-xr-x  2 root root   4096 Nov 20 10:29 .
drwxr-xr-x 73 root root  53248 Nov 28 23:14 ..
-rw-r--r--  1 root root 233536 Nov 10 18:12 libqconnmanbearer.so
-rw-r--r--  1 root root  81224 Nov 10 18:12 libqgenericbearer.so
-rw-r--r--  1 root root 254096 Nov 10 18:12 libqnmbearer.so

There are no helpful messeges of any kind - clicking on "Check Mail" in kmail does absolutely nothing.

I also tried resetting akonadi by following the steps at https://wiki.ubuntuusers.de/Akonadi/#Akonadi-zuruecksetzen (in german) and reconfiguring the IMAP agent. This did *not* fix the problem...

So currently I can't check my mails on my main computer. Help!
