Troubleshooting

• If you encounter the following error:

  PermissionError: [Errno 13] Permission denied
  

  This error typically occurs when the program tries to bind a network socket to a port that requires higher privileges or is already in use. Here are some steps to resolve this issue:

  1. Check if the port is already in use: Use the command netstat -tuln to check if the port is already in use. If it is, you will need to stop the process using that port or use a different port for your application.

  2. Check your permissions: Ports below 1024 are considered “privileged” ports and you need to be a root user to bind a service to these ports. If you’re trying to bind to a port below 1024, try using a port number higher than 1024 or run the program as a superuser.

  3. Run as a superuser: If you need to use a privileged port, you can run the program as a superuser with the sudo command. However, be aware that this can have security implications.

  4. Check your firewall settings: Your firewall may be blocking the port. Check your firewall settings to ensure the port is open.

  5. Change the HTTP_PORT variable: If the above steps do not resolve the issue, you can try changing the HTTP_PORT variable in the main.py file. For example, you can change it to 8000:

     HTTP_PORT = 8000
