How do I fix the "System Error" problem upon signing in to Mac?

You may get this error in these situations:

1. When your device is not connected to the internet
2. When communication with the server fails
3. When there is a country block

Before troubleshooting, please make sure:

• You are connected to the internet via WiFi or LAN.
• To isolate the cause, temporarily disable any third-party app that may interfere with your connection. For example, a firewall with strict settings, another VPN application, or antivirus.

1. Turn the Hotspot Shield ON.
2. Switch wifi ON and OFF.
3. Turn the Hotspot Shield OFF, wait  a few seconds, then turn it back ON.
4. Delete Hotspot Shield Profile
   
   • Go to system preferences on your Mac device.
   • Select Network
   • Select Hotspot Shield.
   • Click "-"  then click Apply.
5. Connect to a different network (for example, if you were connected to Wi-Fi, try connecting to your mobile data network or another Wi-Fi).
6. Open Hotspot Shield > Turn VPN ON
