Getting HTTP HttpResponseException

Getting HTTP HttpResponseException for every API except getVersion().
Below is the exception i am getting:
org.apache.http.client.HttpResponseException: at com.offbytwo.jenkins.client.validator.HttpResponseValidator.validateResponse(HttpResponseValidator.java:11)
at com.offbytwo.jenkins.client.JenkinsHttpClient.get(JenkinsHttpClient.java:152)
at com.offbytwo.jenkins.JenkinsServer.getJobs(JenkinsServer.java:169)
at com.offbytwo.jenkins.JenkinsServer.getJobs(JenkinsServer.java:127)
at Jenkins.main(Jenkins.java:70)
I am just creating the JenkinsServer Object using the URI and username and password and hitting the methods, But getting the above exception.
Seems like it is failing at validating the API. Please Help.

Start in com.offbytwo.jenkins.client.validator.HttpResponseValidator.validateResponse and trace the request path through JenkinsHttpClient.get and JenkinsServer.getJobs. Reproduce the reported behavior using the URI, username, password, and API methods described, then inspect the HTTP response details to identify why validation fails. Done means the affected APIs behave correctly while getVersion() continues to work.
