I have the same code in two places (Dev and Production). On my dev server, I am able to use OAuth with no issues. On my Production server, I get 401 unauthorized every time I make a request.
I tried regenerating my keys, I back tracked through every line of code to figure out if it was me. As far as I can tell, the Twitter servers are rejecting either my server or my keys. Any suggestions? I have customers who want to use my app and currently no one can login.
