ESP32-POE Rev G: eth2ap example does not work

[cn_jetter]

I used the Code from the esp32-POE Github repositiory
https://github.com/OLIMEX/ESP32-POE/tree/master/SOFTWARE/ESP-IDF/ESP32-PoE_Eth_to_AP_v4.4

I'm using ESP32 IDF Version 4.4.0
My IDE is PlatformIO

my Terminal output until I connect a WiFi device is:

␛[0;32mI (3362) eth_example: Ethernet Started␛[0m
␛[0;32mI (3362) eth_example: Ethernet Link Up␛[0m

I (3462) wifi:Init max length of beacon: 752/752
I (3462) wifi:Init max length of beacon: 752/752

when I connect the WiFi device (iPhone, Laptop, Windows Phone) I get:

I tried the Troubleshooting in the example repository and tried to increase the FLOW_CONTROL defines:
#define FLOW_CONTROL_QUEUE_TIMEOUT_MS (200)
#define FLOW_CONTROL_QUEUE_LENGTH (80)
#define FLOW_CONTROL_WIFI_SEND_TIMEOUT_MS (200)

but sadly it didn't help

I tried googling the problem but didn't find anything useful
can it be possible that I need to change a define or anything similar or that PIO may be the culprit?

Thanks for any suggestions

Hello cn_jetter,

Did you ever figure it out and got to deploy a solution?
