Ssh tcp forwarding not working

NETWORKING SOLUTIONS
1

I’m trying to use X11 (tcp) forwarding in ssh on a RUT200.

i.e. ssh -L 8080:192.168.1.87:80 to open a temporary tunnel to a device on LAN.

The client (Ubuntu) respond with the following error:
X11 forwarding request failed on channel 2

As RUT2M is based on OpenWrt and this functionality is active there I tried to add the following in /etc/config/dropbear to no avail:
option GatewayPorts '1'

Is there a way to enable ssh forwarding?

Device is as follows:

-------------------------------------
     Teltonika RUT2M series 2024
-------------------------------------
   Device:     RUT200
   Kernel:     5.4.259
   Firmware:   RUT2M_R_00.07.06.10
   Build:      a64b173fbc
   Build date: 2024-04-02 10:08:23
-------------------------------------

Best regards,

Peter
