No telemetry or command input problem

In Q Ground Control we have video but no telemetry and cannot input any commands to our BlueROV2. The message ‘Waiting for Vehicle Connection’ is displayed. Under the Companion Computer Setup System tab, Pixhawk 1 is a detected serial device and Mavproxy is an active service. Companion software version is 0.0.25. Under Pixhawk Firmware update, ArduSub version says ‘not found’. We have followed the ArduSub troubleshooting guide for No Telemetry (No Autopilot Connection). Working down the list to Check Mavproxy, we have logged into the Companion Computer via web terminal and entered the screen -r mavproxy command. The following message is displayed. Can you help?

I would use something else. That is also likely to cause some conflicts (you request params to and the request goes to the ping360 instead of rov)
