Hello,
same problem here. I had no issues since a long time now the KNX Tiunnel connection to my Enertex KNXnet/IP Router disconnects every day with similar failures as described some posts above. I have updated to the newes 3.4.2. maybe there was an change which produce this problem.
best regards René
I have tried now also different devices running OH3.
