Vehicle 1 did not respond to request for parameters

I am running ArduPilot on BeagleBone Blue for a while now. Running Windows 10 on PC and connecting via WiFi to ArduPilot. Everything was working fine until recently.
Now QGC gives me the following message: “vehicle 1 did not respond to request for parameters”
When i connect using the Android version of QGC i have no problems. Meaning the connection is fine and i receive all parameters.
Any ideas what might be the problem?
