KC868-A8 Ethernet Problem

[msinfo]

Hello, i have a KC868-A8 Board connected with ethernet cable but the port suddenly stopped working. The port indicators are both flashing and the board keeps restating every 15min because it searches for a ethernet connection. I use it with ESPhome and home assistant. If i re-flash the esp32 with a WIFI configuration everything works but when i try to use the Ethernet port i get an error and it goes offline in esphome. (Component ethernet was marked as failed.)
Here is my code -

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

manual_ip:
  static_ip: 192.168.1.154
  gateway: 192.168.1.1
  subnet: 255.255.255.0

Any ideas on how to fix this ?
