Before installing VirtualBox or VMware Workstation, my VPN Connection (L2TP/IPSEC PSK) works without any problems. I'm able to reach every Site I want.
But after one of them are installed I getting this error message at several sites with Chrome (Edge and Firefox won't load too, but without giving me an detailed error message), e.g. the whole StackExchange Network.
My Android Phone didn't have this issue (connected to the same VPN, of course)
I tried all the nice things that i found with google.
flushing/renew/release dns (and other crazy command line commands) -> no success
Set DNS-Server manually -> no success
Even after uninstalling -> no success
2 weeks without Vmware/VirtualBox (after complete Windows-Reset) -> SUCCESS
My question now: Is it possible to get back the functionality without to give up on VirtualBox or Vmware? Any Ideas, some magic spells?
Server = QNAP-NAS
Client = Windows 10
Many thanks.

Twisty Impersonator ask me to run nslookup on an inaccessible-site. Superuser.com is on of them:

VMnet1 is the Internal Network (To connect via SSH without a physical network)
VMnet8 is the VMware Bridge
Connecting to the local Network devices via IP (192.168.0.xx) over VPN works fine.
As i mentioned earlier, the other half of the world wide web is reachable.
Best Answer
Your VPN connection is configured with the DNS server 192.168.0.1. As demonstrated by your nslookup query attempt, this DNS server is the first to be queried by your computer. Apparently your computer does not have a working route to this DNS server when your VPN connection is active. This needs to be resolved.
Based on your comment:
It appears something was not working with your VPN connection and that was preventing you from reaching this DNS server.
