Custom board for LX200V30

Hello! Good day! Tell me, I am developing my own PCB for the LX200V30 module, in my design I cannot use the RJ45 connector with a combined transformer, I have to use an external transformer. I chose H1102NL, but the module refuses to work with it, so I soldered a connector with a transformer, which is installed on the debug board, to the contact pads of the module and everything worked. Tell me where I made a mistake in the design or which transformer do you recommend to use.

And if you have 3D model of LX200V30, please share with me.
