Cannot assign requested address

This error message typically occurs when a program tries to bind to a network socket with a specific IP address that is already in use by another program, or the IP address is not available on the network interface.

To resolve this issue, you can try the following:

1. Check if the IP address is already in use by another program or device on the network. You can use tools like nmap or netstat to check for conflicting IP addresses.

2. Verify that the IP address is available on the network interface by checking the network configuration settings on your system.

3. Check if there are any firewall rules or access control lists that are blocking the program from binding to the IP address.

4. Restart the program or the network interface to see if it resolves the issue.

5. If the problem persists, you may need to change the IP address or network settings to avoid conflicts with other devices or programs on the network.
