hwo can i solve this ?

  1. Reboot the unit
  2. Try a different web browser
  3. Factory reset the device.

thanks jarid , i have tried all of these steps without any result :(:frowning:

I would go to System>Reboot: reboot into the secondary firmware bank. If the issue persists, appreciate if you can go to Status tab and download a diagnostic report and send that to our support team to verify if this is a hardware issue or not.
