Answer 1

To solve your issue please follow the steps:

1. Open your cmd
2. Type as netstat –ano
3. After doing that the list of process with their ports will be opened
4. Now search ‘process ID’ of the port you are unable to use (in my case port 11111)
5. Now simply open task Manager and Stop that process
6. Finally your port is ready to use
