Auth error with code 16

Hi, Ihave generated an api token (in the swagger ui) and put Bearer in front of it. i then authenticate myself and try to list my tenants using the rest api. But I keep getting the error unathorized with code 16.

==> 401

{ “code”: 16, “message”: “”, “details”: }

When I check the token in, I get the message that the signature is not valid

What am I doing wrong?

Thanks for help!
