@CSK- Thanks for stopping by to visit. We welcome you to the Community!!

I can't pinpoint the exact issue with the information you provided but more likely, that error usually means your credentials are miss matched. If you are testing in sandbox, make sure you're using all the correct credentials for that environment and the same goes for when you are in production.

I hope this helps!
