[SalesForce] Issue while authorizing an org : Kill the process running on port 1717

Currently I am unable to authorize an org due to the below error.

Kill the process running on port 1717 or use a custom connected app and update OauthLocalPort in the sfdx-project.json file.

I have tried below solutions but it's not resolved.

Solution 1 : I have tried to kill the process in the task manager but there is nothing running on port 1717.
Solution 2 : In the cmd I tried finding the task by running the command netstat -ano|findstr "PID :1717" and killed the task. but after that getting another error.
