Hi @DSivaperumal and welcome, it’s a pleasure to have you here!
Thank you for reaching out to the HubSpot Community!
Here is an article that might be of interest: “Couldn’t complete the connection: Authorization failed because there is a mismatch between the scopes in the install URL and the app’s configured scopes. Please contact the app developer.”.
Also, these resources might help you:

- The reply from @Mike_Eastwood on this post “Authorization Failed because the install URL does not match the specified scopes.”
