Bing error message

Hi, I am new with Bing translate App but I can't use it. It keeps sending me this error message:

Argument ExceptionMethod : Translate ()Parameter:Message:The Web token must have a signature at the end.The incoming token did not have a signature at the end of the token.message id=5005.V2_Rest.Translate.2BB8C9DC

I registered my application and get both the client ID and client secret.

Please help me to resolve it.
Thanks in advance
