Could you please provide some additional information? Does the server work and then it fails, or does it never connect?

alphaville commented 1 year ago

Most likely, this is because you are trying to connect to a server that doesn't bind to the address you have provided. This is a safety precaution: when you design your TCP interface, you need to provide an IP. If the IP you used there is not 192.168.137.1, the server will not accept requests. You can allow incoming requests at all IPs by using the address 0.0.0.0. However, without looking at your code I cannot tell what the issue might be. I will close this issue for now, but feel free to comment.
