Constant Errors: “Activation of network connection failed”

I have just installed F42WS on 2012 Macbook Pro. working beautifully after a few key combo setups.

One really annoying issue, and I had this with my Dell laptop years ago but can’t remember how i fixed it.

I keep getting constant notifications “Activation of network connection failed”.

I clear it, and it comes back maybe 10-30 minutes later. I am connected to ethernet. No VPNs set up or anything like that. really frustrating. Any advice appreciated. Thanks
