Gaming over a VPN will add latency, similarly, forcing a distant server will also increase latency massively. This will result in a very poor gaming experience. The best thing to do is to avoid routing game traffic through the VPN and ensure you're connecting to a low ping, local server with Geo-filter.

I'm not too familiar with the process on an Xbox, but you may need to go to your Network Settings on the Xbox and set it up again through there. I know you need to do this on PlayStation. Try that and let us know if it's working for you!

Nice work! For Hybrid VPN I'd suggest starting here:

Do let us know if you have any issues.

Don't use WiFi, just use ethernet during troubleshooting for the moment, what do you physically see after putting http://192.168.77.1 into your web browser? Also please try another browser as Safari forces HTTPS which won't work well with the interface.

When did this start to occur? What happens exactly when you access the interface?
