ELEX Stamps.com Plugin Authentication Failure

Customer :

I’m trying to process an order online and my plugin keeps saying my stamps.com authentication has failed. There is money in my account the package is straight forward (just a priority mail package under 2lbs in a 12x9x3 box) worked two days ago and now – not so much.

Support :

Authentication failed error usually appears when the User Id and the password is not correct in the plugin settings

Kindly check the User Id and password.

In case, if the problem persists please contact Stamps.com support to check the details.
