If you have a proxy around your instance and use NTLM authentication with a username and password, the URL trigger plugin is unable to reach external URLs with the following stacktrace

Jenkins now allows for NTLM authentication since the fix for https://issues.jenkins-ci.org/browse/JENKINS-1920 and the URL trigger plugin should use the same proxy configuration.
