Mavlink router parameters download

On a new boat we installed Ardurover 4.3 beta 4 and can’t download parameters. i connect to the cube trough a raspberry running mavlink-router, the mavlink itself connects but it hangs on parameters.
Is there any known issue with mavlink router and the last ardurover releases?

Funny thing is that telemetry arrives but i am just not able to download parameters.


Just tried mavproxy, same problem i have mavlink telemetry but “Getting Params” forever…
