On the drone via Mavrouter (I also used MavProxy) I configured the transmission of telemetry to the server, everything works correctly. I don’t understand how I can connect to the server from my computer to receive telemetry. I tried using UDP with transmission to 0.0.0.0, to 127.0.0.1 and to the server IP, but it didn’t work in all cases. I can’t figure out what the problem is, in the server settings or MavProxy. All ports are open on the server, the ports for receiving and transmitting telemetry are different. This is what MavProxy startup looks like on the server: mavproxy.py --master=udp:0.0.0.0:14550 --out=udp:0.0.0.0:14551
Not sure about the exact configuration on your server, but you can use a reverse SSH tunnel to read the telemetry data from the server to any GCS.
