Exception: org.apache.http.client.HttpResponseException: Forbidden error

Hi,

I'm using this jenkins client to trigger jobs and get the console output. But, since yesterday I'm getting the error
"**Exception: org.apache.http.client.HttpResponseException: Forbidden**" exception when I trigger a job using my existing credentials.

I'm able to fetch details of the job but not trigger a build using the same credentials.

Here's the sample snippet of code i'm using for triggering a job and fetching details from a job.

Triggering a job (Not working)

`String uri = "http://A.B.C.D:PORT/jenkins";
String username = "xyz";
String password = "xyz";
JenkinsServer js = null;

try {
js = new JenkinsServer(new URI(uri), username, password);
} catch(Exception e) {
System.out.println("Exception: " + e);
}
BuildWithDetails buildDetails = null;

try {
JenkinsTriggerHelper jsHelper = new JenkinsTriggerHelper(js);
buildDetails = jsHelper.triggerJobAndWaitUntilFinished("dev-3");
} catch(Exception e) {
System.out.println("Exception: " + e);
}

String consoleOutput = "";
System.out.println("Build details: " + buildDetails.getResult());
System.out.println("Build duration: " + buildDetails.getDuration());
//System.out.println("Build logs: " + buildDetails.getConsoleOutputText());

System.out.println(getBuildInfo(buildDetails.getConsoleOutputText()));
`

I believe it is something to do with authorizations for a user but as far as I know there haven't been any upgrades to the jenkins server we're using.

Any help is appreciated.

Thank you!
