NETWORK IS UNREACHABLE

Hi,

This is my first time posting here, so i'll explain my problem.

i'm using XCode to develop an iOS app, which act as a client and needs to connect to a specific server that I've created on another computer, and it was working fine, but suddenly I got this "NETWORK IS UNREACHABLE" error when running my project.

Even though, my internet is working fine, and I can use my search engines.

So, can someone please tell me what is the problem!!!

I've been struggling with this problem for quite a while now 😟,,, PLEASE NEED HELP!

Best regards.
