Getting HTTP 400 Bad Request when trying to hit LV web service with a GET

[p27]

Going through this tutorial:

https://zone.ni.com/reference/en-XX/help/371361R-01/lvhowto/build_web_service/#Creating_VIs_WS 

Attempting to navigate to the method URL in IE results in an HTTP 400 Bad Request.

I've turned off all firewalls to see if that influences the result, but same issue remains.  I also tried both the application ports and debug (8080 and 8001).

Is there something I need to enable or configure in the environment/LV Web server? 

Thanks

had to change app web server from 32b to 64b

also don't forget to remove the curly braces from the method URL as well...
