Common Issues #
Cause
- 5 GHz network only
- Incorrect password
- Weak signal
Solution
- Ensure WiFi network is 2.4 GHz compatible
- Verify password and re-enter
- Move device closer to router or access point
Cause
- IP address unknown
- Device not on the same network
Solution
- Check router device list
- Reconnect using USB and check current IP address or reconfigure network
Cause
- TCP port 10001 is blocked by firewall or antivirus software
- The TCP port may have been changed from the default 10001 to an unsupported value
Solution
- Allow GHL Control Center in your firewall
- Ensure TCP port 10001 is open and not blocked
- Check antivirus network protection settings
