Hi. I’m using Blokada+ via WireGuard 0.5.3 on my Windows 11 (24H2) PC. When I activate the tunnel inside WireGuard, I lose all Internet access and cannot visit any websites.
I noticed this issue prior to I subscribed to Blokada+. When I was using Surfshark I had the same issue with WireGuard, but was able to connect to their VPN with the OpenVPN Connect client, via UDP / TCP protocol.
Switching device location, DNS provider does not fix this issue. Turning off Windows Defender Firewall also doesn’t fix this issue. I attempted connected to my phone’s personal hotspot, still behaves the same.
My smartphone is using the Blokada 6 application. It was able to access the Internet with the VPN on. Seems like it’s just my PC having trouble with WireGuard.
