I have sort of hit a dead end. Can someone please help. I have never used libwebsockets before. I have an RPI4(Installed Ubuntu 22.04), where my code is running which tries to ping my Laptop(Windows 10). Both are on same Wi-Fi network. I am able to Ping each other through command prompt, however through code it throws an error CLIENT_CONNECTION_ERROR. Same code works properly on Ubuntu 20.04 running on x86_64 Virtual Box. However it does not work when we run it on an RPI4. Here's the error log:
