+++ This bug was initially created as a clone of Bug #53558 +++

If a client is not switched from iTalk to Veyon f.e. opsi rollout failed on this client, the Veyon proxy and the computerroom module will crash or become not responsive. You need to restart both services.

The Veyon proxy app should be robust enough to handle a non Veyon speaking client.
Simply ignore would work, excellent would be a pop up like "Client XY is not configured using Veyon. Please check. Will ignore this client(s)"

Happened in two customer environments already.
