Odd VPN behavior. Can anyone explain?

When I’m away from home, I VPN into my home network to watch my local sports team, using an ISP TV service that is paid for ie, if I were at home sitting in front of my TV, I could watch. I can watch this way for several hours, but after that I get a message that says ‘this content is not available’. Rebooting to get a fresh connection does not cure the situation.

Can someone explain why my time is limited and if there is a solution to my issue? I’m using OpenVPN protocol over piVPN and my ISP/content provider is Verizon.

This won’t help your specific problem, but because you have control over both the server and the client and can thus choose the protocol, I highly recommend using WireGuard instead of OpenVPN. It has a lot less overhead and performance is significantly better. PiVPN supports it.

I have considered reconfiguring the server for WireGuard and maybe this is the opportunity to benchmark the two. Lol, the limiting factor may be the hardware rather than the protocol as I recall the server is a Raspberry Pi 3B

Agreed, my situation would be proof of that.

I have considered watching by way of VNC but the video would be barely tolerable and there is no audio.
