@Vanshika Bhati​ The error usually means that the port you are trying to open is being already used by another application. Try using netstat to see which ports are open and then use an available port.

Also check if you are binding to the right IP address. I assume it would be localhost.

> Check if an application is using your port 8556. If that application or process is another important one then you might want to use another port which is not used by any process/application.

Anyway you can stop the process which uses your port and let your application take it.

Command "netstat -tulpn" will enable one to find the process ID of that is using a particular port.

If it is linux environment try the below commands

Use netstat -tulpn to display the processes

kill <pid> This will terminate the process

If it is windows environment try the below command on cmd prompt

Use netstat -a -o -n to check for the port usages

Use taskkill /F /PID <pid> to kill that process

Please let me know how it goes. Thanks!
