“No regions found” usually points to a connectivity issue. Please try:
- Run the game as Administrator.
- Press F11 to view ping and network debug info.
- If you’re in a disconnection loop, try switching servers.
- For long matchmaking searches, wait up to 15 minutes. If no match is found, restart the client and ensure your expedition is planned and a Trampler is selected.
- Check your Firewall/Antivirus and allow the game.
- Use a stable, wired internet connection if possible.
- Try a different network (e.g., mobile hotspot) to rule out ISP issues. You can also test backend access by opening this page in your browser: https://developer.microsoft.com/en-us/games/products/playfab/
