I am using the authentication API as directed here: http://docs.microsofttranslator.com/oauth-token.html
Everything was working fine for about a week and suddenly today at around 11:55pm eastern time, all calls to get a new token give 500 errors with the following stack:
We simply make a POST request to https://api.cognitive.microsoft.com/sts/v1.0/issueToken with header 'Ocp-Apim-Subscription-Key' set to our key
I tried using our second API key, and it still does not work. I tried regenerating another key, and it still does not work. Our account manager says that the account should be in good standing.
Thank you
