When requesting an access token from https://login.salesforce.com/services/oauth2/token, I get the response:

unknown error, please retry your request

I seem to be making a well-formatted request with proper credentials, but I get this mysterious error.  Has anybody seen this and can anybody help?

Many thanks,
