Hello All,
I am trying to Create a Hello World Lightning Web Component as mentioned in the URL below.
Hello World Lightning Web Component (https://trailhead.salesforce.com/content/learn/projects/quick-start-lightning-web-components/create-a-hello-world-lightning-web-component?trail_id=build-lightning-web-components)
But in VS code I am getting below output and did some analysis but unable to risolve it please help me how can I proceed further.

VS code output:
Starting SFDX: Authorize an Org

09:42:18.175 sfdx force:auth:web:login --setalias vscodeOrg --instanceurl https://login.salesforce.com --setdefaultusername
ERROR running force:auth:web:login:  Cannot start the OAuth redirect server on port PortInUseAction. 

Try this: 
Kill the process running on port 1717 or use a custom connected app and update OauthLocalPort in the sfdx-project.json file.
09:42:23.367 sfdx force:auth:web:login --setalias vscodeOrg --instanceurl https://login.salesforce.com --setdefaultusername ended with exit code 1
------------------------------Sometimes below error is coming-------------------
use a custom connected app and update OauthLocalPort in the sfdx-project.json file

Thanks in Advance :)
