Paypal returned an unexpected error: HTTP 401

I get this error when i click "Pay With Paypal" I activated Live in Paypal and insert the credentials into the module.

I do not get this error in Sandbox.

The credentials are correct I have triple checked and also my paypal account permissions allow for payments.

Any guidance appreciated

Can you show the latest log from the logs/ folder? It will contain the error description.
logs/http_request_last-...paypal...log

Mask sensitive data.

Thanks for replying, I just created new app in paypal and used those credentials and they appear to work ok. Sorry about bothering you.
