Mavlink2REST not receiving events

Hi,
I have installed mavlink2rest on my Ubuntu 19.10 laptop. It is working fine with SITL autotest. I can see events and execute some requests successfully.

But when I plug the ROV with the tether, there is no incoming events on: 127.0.0.1:8088/mavlink (“mavlink2rest -v” does emit any message). Same on: 192.168.2.2:4777/mavlink -> reponse is empty {}
But QGC can still connect and control the ROV.

Recently, I have upgraded the companion software to version 0.0.22 and kept Ardub version to 3.5.4. I have also upgraded mavlink2rest on the PI companion to version 0.9.0. The service is active according to 192.168.2.2:2770/system

Is there something I missed ? Any ideas ? Thank you.

Note, I have not modified the default network configuration:

–master=/dev/autopilot,115200
–load-module=‘GPSInput,DepthOutput’
–source-system=200
–cmd=“set heartbeat 0”
–out udpin:localhost:9000
–out udpout:localhost:9002
–out udpin:0.0.0.0:14660
–out udpbcast:192.168.2.255:14550
–mav20
–aircraft telemetry
–streamrate 10

I had a similar issue and it was because the SERIAL0_PROTOCOL value for the PixHawk was set to MAVLink1 and it should be set to MAVLink2 in QGC.
