PayPal exception with .NET API: Stream was not readable

Question

Trying to process payments, but my customers are getting an exception. When I step through the payment process, I see this exception when I attempt to obtain an Access Token using the OAuthTokenCredential method:

Exception in HttpConnection Execute: Stream was not readable.

This was working just a few days ago. I did update some things on my site, but have not touched the PayPal code, nor have I changed the ClientId and ClientSecret credentials. Any thoughts on what might be happening? Thanks.

Something broke on PayPal's end and they had to release an update to their PayPal REST API. Use NuGet to download the updated API references and it fixes the issue.
