Web server failed to start. Port 7002 was already in use.

There could be various reasons why the web server failed to start and the port 7002 was already in use. Here are a few possible solutions you can try:

1. Check for running processes: First, you need to identify which process is using port 7002. You can use the following command in the terminal to check for any processes running on that port:

   lsof -i :7002

This will give you the process ID (PID) of the process using port 7002.

2. Stop the conflicting process: Once you have identified the process using port 7002, you can stop it using the following command:

   kill <PID>

Replace `<PID>` with the actual process ID you obtained from the previous step.

3. Change the port number: If you can't stop the conflicting process or if it's necessary to keep it running, you can change the port number for your web server. Look for the configuration file of your web server (e.g., Apache's httpd.conf or Nginx's nginx.conf) and modify the port number to an available port, such as 8000 or 8080.

4. Restart the web server: After making the necessary changes, restart your web server and check if it starts successfully without any port conflicts.

If none of these solutions work, please provide more details about your web server setup and any error messages you encountered, so I can assist you further.
