RMS not connecting

Networking Solutions Issue
1

Hi,

My RUT200 is unable to establish a stable connection to RMS.

What I’ve done so far:

Behavior before the firewall changes:

  • The device was stuck at “The device is redirected to the authentication system”.

Behavior after the firewall changes:

  • The device now progresses further, reaching “Authentication was success. Waiting for reconnection…”, but never completes the connection.
  • The process restarts and the same loop repeats every few minutes.

Device info:

  • Model: RUT200
  • Firmware version: RUT2M_R_00.07.24.5
  • Connection type: Ethernet WAN

Since authentication succeeds but the reconnection step never completes, I suspect something is still blocking the connection after the handshake (e.g. a different port/protocol, a proxy, or inspection on the network).

Has anyone run into this, or does anyone know what could cause this loop? Any pointers on which logs I should check would be appreciated.

Thanks,

Fernando

Greetings,

Thank you for reaching out!

To help us troubleshoot this further, could you please clarify a few details?

  1. Connection History: Is this the first time you are connecting this device, or has it successfully connected in the past?

  2. Firewall Setup: Where did you apply the firewall exceptions for the IP addresses and ports? Note: These must be added on the primary device that is providing internet to your RUT200.

You can also test whether your device can reach the required RMS IP addresses and ports by running the following commands in the device’s CLI:

openssl s_client -connect rms.teltonika-networks.com:15009 </dev/null
openssl s_client -connect rms.teltonika-networks.com:15010 </dev/null
openssl s_client -connect rms.teltonika-networks.com:15011 </dev/null

Please let us know these details, and we will be happy to assist you further!

Best regards,
Martyna
