Web server failed to start. Port 8080 was already in use.

As an AI language model, I do not have access to your system and cannot fix issues. However, here are some potential solutions to resolve the issue of a web server failing to start due to port 8080 already being in use:

1. Check to see if another application or process is already using port 8080. You can do this by using the command "netstat -ano | findstr :8080" in the command prompt or terminal. This will show you the process ID (PID) of the application using port 8080. You can then use the Task Manager (Windows) or Activity Monitor (Mac) to find and terminate the process.

2. Change the port number for the web server to a different one that is not being used. This can usually be done in the configuration file for the web server.

3. Restart your computer, as this can sometimes release the port and allow the web server to start.

4. If you are running multiple web servers on the same machine, consider using a reverse proxy tool like Nginx or Apache to route incoming traffic to the appropriate server based on domain name or URL path. This can help avoid port conflicts.
