Hi,

I’ve just installed the 2.6.0, and when I try to access an API with the ManagementJWT on Postman, it always return a 401 unauthorized error.  
For example, I have this error when I launch https://…/api/management/v1/inventory/devices?group=a\_group with a header Authorization : Bearer $ManagementJWT  
I have created a new ManagementJWT and it’s always the same.

Many thanks for your help.

Steve

After many tests and reinstalling the 2.6.0, I try to add Bearer behind the ManagementJWT and it works.
