Works great when its working

It was working great until every time I try to translate something this pops up "ArgumentException: The Web Token must have a signature at the end. The incoming token did not have a signature at the end of the token. : ID=5107.V2_Json.Translate.20AE3706" Im not sure why or what this means. But when its not doing that then it works great.
