Fixed: In HA environments errors could occur, when the ICG was disconnected and then connected in the UMS Console.
Fixed: Devices did reconnect every 30 minutes.
Changed: Improved error handling for the management websocket connection between UMS and ICG.
Changed: When a shadowing/secure terminal action is triggered but the forwarding of the device portforwarding event fails, the UMS closes the portforwarding websocket to the device.
