Thanks for your quick reply! This error occurs consistently no matter what nonce I'm using. My timestamp appears to be aligned with the time from your response. I also tried a different nonce scheme and that didn't seem to work either.
Here is my post body: status=My%20Tweet I just attempted to use a + instead of the %20 but that did not work. I'm at a loss as to what it could be. Maybe I'll try yet one more nonce scheme? Is the any scheme in particular that you have found to work? Thanks!
