I’m getting a 401 error when sending a request from one server, but not others. Is it possible that the IP I’m on is blacklisted?
I am able to request tokens just fine on other servers using the same code.
Issue resolved: it turns out the system time on my server was incorrect.
damn… I have spent all day to figureout this - THANK YOU MAN !!!
