I am having only step in the build plan which is Make http call to jenkins

<host>:<port>/job/FitterfoxScalaServer/buildWithParameters?token=1OzdTFiIs2&DIFF_ID=D5&PHID=asda

and this is a get call which works when i hit it from the browser or rest api client. But when i execute the build step, it is stuck in pending state and the api call is also not made since the job is not triggered in the jenkins. Could some one guide me through the way to debug this.
