Web server failed to start. Port 63040 was already in use.

There could be a few reasons for this issue. One possibility is that another process is already using port 63040 on your server. You can check which process is using that port by using the following command:

netstat -ano | findstr :63040

This will display the process ID (PID) of the process using the port. Once you have the PID, you can identify the process in Task Manager (on Windows) or using the `ps` command (on Linux) and terminate it if necessary.

If you have confirmed that no other process is using the port, it's possible that your web server configuration or application code is causing the issue. You can try changing the port number in your server configuration file or check for any errors in your code that might be preventing the server from starting.

Lastly, it's also worth considering if there are any firewall or security settings blocking access to the port. Ensure that the necessary firewall rules are configured to allow incoming traffic on port 63040.

I hope this helps resolve the issue with your web server not starting. Let me know if you have any further questions!
