was configuring the voxl-mavcam-server service when enabling it together with voxl-streamer on my Drone Seeker MRB-D0003-2-V2-C7, Qgroundcontrol stopped working, started connecting and disconnecting where it finally sent the following error message

"Vehicle 1 did not respond to the parameter request. This will cause QGroundControl to be unable to display its full user interface."

@Ariel-Saez So if you go back and disable the voxl-mavcam-server service and reboot does QGC start working normally again?

@Eric-Katzfey I try the factory_reset and disable config for both mavcam and voxl-streamer and the error is still happening

@Eric-Katzfey I Still can't fix the error, I try installing a older version of sdk, but didn't fix it, also I check the console on the QGroundControl and it shows "Error writing to QHostAddress("192.168.8.1") "14550"

@Ariel-Saez Okay, so the connection issue isn't related to voxl-mavlink-server or voxl-streamer then. How are you configuring your WiFi? Is it using the default SoftAP mode where the drone acts as an access point? If so, are you connecting the computer running QGC to the drone's WiFi network?

@Eric-Katzfey Hello, yes I use the voxl-wifi -f comand to configurate the wifi.

 Is posible, that the flight core 2 has been damage? or someting, or it's a configuration problem?

because it's am worried when I try the usb connection with the same problem.
