AME WebService API jobstatus

Hello

Now I am trying to get information from AME using Adobe Media Encoder WebService, but I am unable to get it successfully.

I could get the server information at http: // {IP}: 8080 / server, but the JobStatus part is Not Found.

<payload version = "1.0">
<ServerIP> {IP} </ ServerIP>
<ServerPort> 8080 </ ServerPort>
<RestartThreshold> 0 </ RestartThreshold>
<JobHistorySize> 100 </ JobHistorySize>
<ServerStatus> Online </ ServerStatus>
<JobStatus> Not Found </ JobStatus>
<JobId />
<JobProgress />
<Details />
  </ payload>

job / history had the same result.

Is there a way to solve these?
Thank you.
