Hi there! I understand you've been seeing a Wi-Fi connection error with The Grand Mafia app for about three days, and it keeps saying there's an internet issue. Let's work through this together.

First, just to clarify:
- Are you using Wi-Fi only, or does this also happen if you switch to mobile data?
- Can you access other internet sites or apps on your device without trouble?

This will help me pinpoint if the problem is with your device’s connection or with The Grand Mafia app itself.

Meanwhile, here are some steps to try:

1. Restart Your Devices
- Restart your PC and your Wi-Fi router. This refreshes your network connection and often clears temporary glitches.

2. Check Your Internet Connection
- Make sure your PC is definitely connected to Wi-Fi and that you can browse websites normally.
- If possible, try switching to a different Wi-Fi network or a mobile hotspot to see if the game connects there.

3. Disable VPN/Firewall Temporarily
- Sometimes, VPNs or strict firewall settings block game servers. Try disabling these temporarily to test if it's the cause.

4. Clear App Cache or Reinstall
- Since you're using Windows with a WebKit browser, clear your browser cache and cookies related to the app or the game’s website.
- If the game is a standalone app rather than browser-based, try reinstalling it.

5. Check for Server Issues
- Occasionally, The Grand Mafia servers might be down or undergoing maintenance. You can check official Facebook updates or community forums to see if there’s a known outage2.

If you’ve tried any of these already, please let me know which ones. That way, I can suggest more in-depth troubleshooting.

Are you satisfied with this solution so far? If not, I’m happy to keep helping!
