Not able to connect/interacts ERPNext with LinkedIn Developer app for sharing the post on LinkedIn

I am trying to connect ERPNext with LinkedIn company page for Social media Posting Via devlopers.linkedIn.com connector. When I try to “Save” after adding “Company ID”, “Consumer Secret”, “Consumer Key” at CRM - LinkedIn setting in ERPNext, it is giving me following error “Bummer, something went wrong. The redirect_uri does not match the registered Value” (can see at attached image)

Which URL should I add at the section of “Authorized redirect URLs for your app” at Developer.linkedin app? (can see at attached image)

Please help to resolve this error.

Thank you!

I have already followed and gone with those steps preciously. But at the end I have received that error. What must be the issue?
Is it because of URL issue?
or do I need premium LinkedIn account for integration?

Any update regarding this ?
