Telemetry not working

Hi, I have got a problem with telemetry on OpenHD v2.0.8 using VEYE MIPI 327E camera. The upload power in OSD shows N/A and I cannot connect to Mission Planner over WIFI on the ground station. It looks like the telemetry works one way only, but the remote control commands get delivered to the AirPi - I can control the drone in the air. All work as expected when I replace VEYE camera with a standard Raspi camera. Any suggestion on how to debug or diagnose the problem?
