TRB142 Mobile restart during remote web access via HTTPS

Networking Solutions Issue

Hi,
I’m having a problem with my TRB142 modem. When I try to connect remotely (via VPN) to the web interface using https, the modem restarts, which resets the connection. This makes remote access impossible. Other protocols like SSH, server port, etc., work correctly.
Are you familiar with this problem and can you help me?

Thank you in advance.

Greetings,

Could you please clarify which firmware version is currently running on the device?

Additionally, could you provide more details about the configuration on the TRB142? Specifically:

  • Which VPN protocol is being used?
  • Are there any custom scripts running on the device?

Please navigate to System → Maintenance → Events Log and send the logs recorded before and after the reboot. Don’t include any sensitive information.

Best Regards,
Justinas

Hello,
The problem is affecting a portion of our network (6 out of 15 modems).

The version is TRB1_R_00.07.19.4, but we are experiencing the same issue on TRB1_R_00.07.10.
The VPN used is OpenVPN, and there are no specific scripts involved.

Best regards.
