Unable To Connect to RCGroups.com / PIA VPN

The last couple of days I've been having repeat problems with connecting with rcgroups.com with my VPN on. I've been hitting that website for four or five years. Nothing significant has changed in my setup and it seems to be cross-platform. The machine I'm on now:

HP EliteDesk

Linux Mint 20

Browser - Firefox / Chrome / LibreWolf

PIA VPN

and

Micro$oft Surface Go 2

Windows 11

Browser - Firefox / Chrome / LibreWolf / Edge

PIA VPN

With the VPN ON, I get a blank white page. Nothing stating that the IP Address if forbidden.
If I turn the VPN off, I can connect with any of the browsers.

Anyone else running into this with PIA? Any ideas to get around it? It's a PIA (Pain In the A22) to have to switch it off for a website. OK, not a PIA, but inconvenient.
