jira-rest-java-client is always Connection refused

[qingbo meng]

I am using jira-rest-java-client to operate jira in my java program.

code like

JerseyJiraRestClientFactory factory = new JerseyJiraRestClientFactory();
URI jiraServerUri = new URI("my jira uri");

JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "username", "pwd");
NullProgressMonitor pm = new NullProgressMonitor();
Issue issue = restClient.getIssueClient().getIssue("TES-1", pm);

the code directly connect to jira url without proxy, why is always Connection refused??

Is the Remote API calls turned ON in the JIRA instance?

The reason for the problem is that you may be getting some network block. I recommend checking with your network administrator.
