No internet access after disconnection from OpenVPN

I have an annoying problem with my Fedora 34.
Whenever I disconnect from VPN (OpenVPN connection from Windscribe) most of the times I lost my access to the internet and I have to restart my laptop to regain my access to the internet (There were couple of times even after restarting my laptop, I still did not have working connection so I had to restart couple of times!)
I don’t know what’s causing this issue. I even checked my DNS with cat /etc/resolv.conf but it showed the default dns
Any suggestion?
