When I restart the 3CX-Debian 15.5.5 Hyper-V VM form the Debian console, the system restarts as it should. But the service "3CX PhoneSystem 01 SIP/RTP Tunneling Proxy" is not responding to clients. On the dashboard, the service is reported as up and running. But no connection can be established to the IP-port 5090. After restarting "3CX PhoneSystem 01 SIP/RTP Tunneling Proxy" solely, the system works as it should.
