Facing Mavlink loss in Herelink air units

Hi all,

I’m facing a serious MAVLink loss issue between two Herelink units:

One Herelink ground unit is connected to QGroundControl via Ethernet.

The second Herelink is mounted on the drone (air unit) and connected to the flight controller.

The ground unit reports up to 95% MAVLink packet loss. This makes telemetry data extremely unreliable or completely unavailable.

Has anyone encountered similar issues when using Herelink-to-Herelink telemetry relay? If so:

What steps helped reduce the packet loss?

Are there any known compatibility issues when using Ethernet with Herelink for QGC?

What logs or settings should I check to debug this further?

Any suggestions or insights would be highly appreciated.

Thanks in advance!
