Issue: This error occurs when the application does not have sufficient permissions to access the specified port or when the port is restricted by the system.
Solution:
- Run as Administrator: Ensure the application has the necessary permissions by running it as an Administrator.
- Disable Windows Firewall Temporarily: The firewall might be blocking access to the port. Disable it temporarily to check if the issue is resolved.
- Review Security Software: Check if any third-party security software is preventing access to the port and modify its settings accordingly.
