I am using Stm32f303-RE model. I have a Wiznet5500 ethernet module in my hand. I want to create a tcp client with the module and see it as a server on the computer(i have server in visual studio and its working . i checked .) and exchange information between the two and ı use Stm32cubeide .I have created this code using a few reference sources and application notes from wiznet. But the code is stuck at in connect() function , I couldn’t find the solution. . i cant connect to my server . Although I have reviewed the old topics in the forum, I have not found a solution that works for me.

I tried to detect the problem with the wireshark program, but the message I see is always in the same application. What is the problem in connect fuction ? I would be glad if you could help.
and by the way im using this connection :
3.3V ----> 3.3v on stm
mosi — > mosi on stm
miso ----> miso on stm
clk --------> spi’s clk on stm
gnd --------> gnd on stm
csn ---------> spi’s cs on stm
im not using reset pin on wiznet . Are these connections enough?
thank you for all becky !
This problem about the FANTASTIC WINDOWS. This issue coming from FANTASTIC WINDOWS FIREWALL. And solution do not use windows. When i used my personel home modem, fix all of bugs errors. All of thing. Connect your wiznet module to your home modem or your router or something like that. If u connect to directly your PC, you can not use this module. Because FANTASTIC WINDOWS FIREWALL.
