Cannot assign requested address

"Cannot assign requested address" is an error message that typically occurs when trying to bind a socket to an IP address or port that is already in use or not valid. It can also occur when trying to assign an IP address that is not available in the network range. Some common causes of this error include:

1. Another process is already using the IP address or port that you are trying to bind to.
2. The IP address that you are trying to assign is not available in the network range.
3. The network interface that you are trying to use is not enabled or configured correctly.
4. Your firewall or security settings are blocking the connection.

To resolve this error, you can try the following:

1. Check if there are other processes using the IP address or port that you are trying to bind to and terminate them if necessary.
2. Verify that the IP address that you are trying to assign is available in the network range.
3. Check your network configuration and ensure that the network interface is enabled and configured correctly.
4. Temporarily disable your firewall or adjust your security settings to allow the connection.
