Unable to adds a user using userService plugin

HI,

I am facing issue with the Openfire version 4.6.2 after uploading userservice.jar (2.1.2)

I have Enabled - User service requests will be processed and also define the Secret key auth and saved.

Now while creating the user using the api :- " http://x.x.x.x:9090/plugins/userService/userservice?type=add&secret=******&username=abc&password=test&name=akash&email=akash.rana@innefu.com "

It gives me the error http 404 web page not found.

Note:- It is working fine with Openfire 4.2.3

Please help me out.
Thanks
