Getting Response [401] from REST API

Anyone know why I always get HTTP 401 Unauthorized response if I add any parameter to the REST URL

for example works fine but returns 401 error. I got similar errors on every REST API that I am using.

It doesn’t seem to be a permission problem because the URL without parameter works. and it only fails when I add parameters after the ?
