我已经提到了所有可能导致这种情况的原因，但无法查明我的案情的原因 An existing connection was forcibly closed by the remote host

public class JRC {
        public Issue getIssue(String issueKey) throws Exception {
            final URI jiraServerUri = new URI("domain/JIRA/");
            final JiraRestClient restClient = new AsynchronousJiraRestClientFactory()
                    .createWithBasicHttpAuthentication(jiraServerUri, "user", "password");
            Promise issuePromise = restClient.getIssueClient().getIssue(issueKey);
            return Optional.ofNullable((Issue) issuePromise.claim()).orElseThrow(() -> new Exception("No such issue"));
        }
}
