Two W5500 TCP problems communicating with each other

Hi,guys
Two W5500 TCP protocols communicate with each other, one as Client, the other as Server, the Client sends data to Servere, data error occurs from time to time, the amount of data sent and received is the same, the location of data error occurs the same

Such as:

Data sent from Clent side: “0x57 0xab 0x04 0x01 0x00 0x04 0x03 0xbf 0x02 0x00”

Data received to the Server side “0x57 0xab 0x04 0x01 0x00 0x03 0x03 0xbe 0x02 0x00”
