bind: Address already in use

This error message typically occurs when a port or socket is already in use by another process or application.

To resolve this issue, you can try the following solutions:

1. Identify the process that is using the port or socket and stop it. You can use the "lsof" command to list all open files and ports, and then use "kill" to terminate the process.

2. Change the port or socket that your application is trying to bind to. You can modify the configuration file or command line arguments to specify a different port or socket.

3. Wait for the other process to release the port or socket. Sometimes, the process might be in a temporary state, and the port or socket will become available after a while.

4. Reboot your system to release all ports and sockets. This is a last resort and should only be done if all other solutions have failed.
