TCP Connection Problem
-
Hello all, I hope you're doing well !
I have written a program in QT providing TCP Server-Client connection. From the server, I am starting to listen a port. From client, I am entering the IP address and the port to connect to the server.
It works flawlessly when I try to connect to a computer by typing its IP address. However, although I have build the exact project into another pc, I cannot connect to its IP address from any other computer. Even if I disconnect from the wi-fi and connect to my phone's hotspot to change its IP address, I still cannot connect to it from any other PC. Looks like the problem is about this computer. In brief, I can use it to connect to other computers, but it cannot be a server to welcome the other TCP clients.
What might be the problem, and any ideas to fix it?
Thank you in advance!

If you can ping the other computer then it's maybe the firewall.

@Christian-Ehrlicher Once again you are right sir, I have disabled the firewall, and now it allows connections from other devices.
