Hi there! I see you’re connected to WiFi, but the Lightning Link Casino Slots app is showing an "internet connection lost" message even after restarting. Let's work through this together.

First, can I confirm a couple of things?

1. When you say you restarted, did you restart just the app, or also your Mac and the WiFi router?
2. Are other internet-dependent apps or websites working fine on your Mac?
3. Are you using any VPN or firewall software that might affect connectivity?

Meanwhile, here are some steps you can try on your Mac (OS X 10.15.7):

1. Forget and Rejoin WiFi Network:
- Click the WiFi icon > Open Network Preferences.
- Select your WiFi network and click “-” to remove it.
- Then reconnect by selecting the network and entering your password again. This can refresh the connection credentials.

2. Renew DHCP Lease:
- In Network Preferences, select your WiFi and click “Advanced.”
- Go to the TCP/IP tab and click “Renew DHCP Lease.” This can reset your IP address and connection settings.

3. Check App Permissions and Network Access:
- Go to System Preferences > Security & Privacy > Firewall.
- Ensure your app or related services are allowed. If the firewall is blocking the app, it could lose connection.

4. Clear App Cache or Data (if applicable):
- Some apps store cache data that may get corrupted. Depending on the app's settings or support, clearing cache or reinstalling might help.

5. Test on a Different Network:
- If possible, try connecting your Mac to a different WiFi or use a mobile hotspot to see if the app can connect. If it works there, the problem is likely with your router or ISP.

6. Check for App Updates:
- Make sure your Lightning Link Casino Slots app is updated to the latest version, as older versions may have connectivity bugs.

If you’ve already tried these, let me know which ones so I can guide you to deeper troubleshooting. Sometimes, internet connection issues like this can be due to temporary server interruptions as well, but we can narrow that down after these checks.

Are you comfortable trying these steps? Also, did you notice if any error message other than "internet connection lost" pops up?
