Identifying the Issue

The "cannot assign requested address" error typically occurs when an application attempts to bind to an IP address that is not assigned to the server. This error can also occur if the IP address is already in use by another process.

Solution

To resolve this error, you need to determine which application is attempting to bind to the IP address and reconfigure it to use a different address. You can use the following steps to troubleshoot the issue:

1. Check the server configuration to verify that the IP address is assigned to the server.
2. Use the netstat command to identify which process is using the IP address.
3. Stop or reconfigure the application that is using the IP address to use a different address.

In my case, running the chromedriver with the --verbose flag helped me identify the issue. The error message indicated that the chromedriver was attempting to bind to an IP address that was not assigned to the server. I reconfigured the chromedriver to use a different IP address, and the error was resolved.
