Setting up a monitor with web token gives a configuration error

I have sucessfully set up a web token from `configuration profile`. I can see the received token also. But when I try to use this token when creating a monitor i am getting a configuration error. The error says The `request requires user authentication`. The monitor is a GET request. I just selected the web token name from the Authentication method. Do I have to do something else to fix this issue?
