Hi,
We saw the exact same error on July 17 when trying to get a new access
token. Since we have never seen it before, and it happened on the 17th, I
was wondering if it was possibly triggered by errors from this other
thread: "Failed to refresh access token. { "error" : "invalid_client" } on
perfectly good client"
<https://groups.google.com/forum/?fromgroups=#!topic/adwords-api/LuT8mGtYKTY>?
Unfortunately we didn't log any of the HTTP request/responses so I do not
have anymore information but the error did go away later in the day.
Thanks,
Stacie
