Works on Android 13 phone, Brave browser, NordVPN NY server.
Pre-VPN I got the "error" page, post-VPN I just refreshed the page and it loaded correctly without needing to clear cookies.
EDIT: I tried again with a server in KC instead of NY and now the error came back.
Tried clearing cookies then connecting to an "obfuscated" server in NY but still no dice.
They're taking this geo-blocking thing just a wee bit too seriously.
