Ethernet magjacks have many different pinouts. There is no official or de-facto standard.
During Teensy 4.1 development, we used UDE RB1-125BAG1A, which has a completely different pinout from...
Which ethernet magjack did you solder to your PCB?
Design looks correct for Cetus J1B12111CCD or Link-PP LPJ4012AHNL (the 2 possible parts used on the ethernet kit - PJRC has used both of these...
