Jami - Linux & Android - Requires Toggling Offline/Online (Disable/Enable)

Hardware Settings: No power saving, LAN always connected

Jami Settings: DHT Proxy enabled, TURN enabled, UPnP enabled

Issue found on at least two devices, one running Ubuntu 20.04 lts, the other Kubuntu 20.04 lts.

Issue: Text messages seem to flow, but file transfers and calls will not always connect unless the accounts at both ends are toggled Disable/Enable. It feels like Jami "goes to sleep".

The only work around I've come up with is to have a timed job which runs a script killing and re-starting Jami every 20 minutes. 20 minutes appears to be the optimum timing; much longer and Jami is more often offline, much less and Jami becomes awkward to use. This comes close (but not 100%) to keeping Jami online permanently. However, it isn't a very convenient method.
