Hello,
I am using F39, and for a few weeks now, I am having issues with one specific Wifi network.
What happens is, that when connected to the network I am not able to access the internet.
If I turn on my VPN to that network (WireGuard VPN to a Fritz.Box), I can access the internet.
I do not understand this, because I should already be in the same network even without the VPN.
It also seems like DNS can be resolved, even when the VPN is not on.
This problem is really weird, and I hope someone can help me understand it better.
I appended outputs for some commands that might help. If you need further info I am happy to provide 
nslookup with VPN ON
nslookup google.com
