I've taken care of this today and I can assure everyone that it will be fixed in the next general game update, if not earlier in a hot-fix update.
Re-Volt Zone used to have an endpoint for fetching IPs which the game used internally to show your public IP in-game. I've created and deployed an alternative service over at
https://rvgl.rva.lat/fetch_ip which seems to have worked out nicely.
Sorry about the inconvenience. Sad to see RVZ go too
