Building an app that has been working for 3 months now, up to and including last night. No changes made to any code, but today I cannot successfully use oauth/access_token. I receive error 401:<?xml version="1.0" encoding="UTF-8"?> /oauth/access_token Invalid / expired Token
As I said, I have not changed anything and this worked as of 3AM last night. What’s going on?
