Unable to import result through Jenkins job

I m trying to import testng-result.xml through Jenkins job, I have entered correct details and it worked for first time but then its getting failed on every run with below error :

 <div class="aui-message aui-message-warning warning">
                            <p>Encountered a <code>&quot;403 - Forbidden&quot;</code> error while loading this page.</p>
                            <p>Basic Authentication Failure - Reason : AUTHENTICATION_DENIED</p>
                            <p><a href="/secure/MyJiraHome.jspa">Go to Jira home</a></p>
                        </div>
