[jitsi-users] jitsi won't login in the morning after sleep

We have a continuing problem with 2 workstations.
Every morning when they wake up, jitsi is not logged in to the server (ejabberd).
To reach them, I have to call them on the phone and remind them to enter their password into jitsi.

I have 5 other workstations that work perfectly, and this seems to be tied to sleep / hibernation.

We reinstalled jitsi, and tried installing as "administrator". Nothing has helped.
