401 Request token error on only one Consumer Key


The exact same code works for one consumer key but not another one My app receives a 401 response from the request_token call with the error message set to Request token failed

The consumer key is: 6a8182Qpc0w4WM6SqY8gG121B

Both consumer keys specify a redirect and both consumer keys have a redirect setup in the key settings on twitter. I doubt its the signatures as this code has been working fine for several years now with both consumer keys then all of a sudden this popped up.
