Perform the following steps one by one:
- Make sure your internet connection works properly—for example, check the connection from another device on the same network.
- Run a network check on the device itself: go to Settings → Network and press the red button to launch the “Network Check” parameter.
- Restart EVOBOX—some connection errors can be resolved after a system reboot.
Try connecting to a different network, such as a mobile hotspot from your smartphone.
If the error persists, contact Studio Evolution support.
