WIZ550S2E not reconnecting to TCP server

Question

Hello! I’m using WIZ550S2E to connect to a TCP server (Hercules). The problem is that it does not reconnect if I close the server and open it again or if I plug out the cable and plug it in again. You can see my configuration on this topic: Data mode not working on WIZ550S2E WIZ550 Series Hi! I’m trying to connect my MSP432 microcontroller to a TCP server (Hercules) using WIZ550S2E. I configured the module as a DHCP client. The problem is that after switching to data mode, it does not transmit data received from UART or from Ethernet (TCP server). I have attached a logic analyzer capture which can be opened using the free Salae Logic Pro software. You can see that after switching to data mode, it replies success “[S]
”, but the data sent over UART (“abc”) does not reach the T… Why is it not reconnecting? And how can we resolve this issue?

Hi. Sorry, It don’t open capture file. Is it wireshark tool file? please refer to wireshark file to me. I want know your all configuration system diagram or real pictures. Are you normal working configuration tool search? Then It is normal working. Therefore, Which use to serial system?(rs232 or rs485) Or you have to checking to configuration network setting (IP, subnet mask, gateway, port). Please tell me all information. Thank you.

Hi If you run with virtual machine in PC, you must turn off to virtual machine. Thank you

I am not using virtual machine. However, the most important question is why doesn’t WIZ550S2E reconnect if the Hercules server is closed and opened again after a few seconds? It only reconnects if I unplug cable and then plug it again.
