Are you running the program as root?

If you are not running as root, you cannot bind any program to ports bellow 1024. They are considered privileged ports, and only root can use them.

If you want to run as root, don't. Running as root can create problems if someone exploits your program and gets a shell, and discovers it's a root shell.

Run as an unprivileged user, and change the port from 80 to something above 1024.

  • I don't know your application, so you will have to discover on the configuration options or files where to change the port.

  • If you can run the application with a debug log setting, you can pinpoint exactly where is the problem. Otherwise nobody can really help you.

From man 7 ip

ERRORS
       ...

       EADDRNOTAVAIL
              A  nonexistent  interface  was  requested  or  the  requested source
              address was not local.

You've probably mistyped the listen IP address to bind to in the config.
