I'd suggest to add a logger to gather as much details as possible using the UI: - https://wiki.jenkins.io/display/JENKINS/Logging
IIRC, long time ago I had some issues with the Jira plugin something related with the restapi and login, but the only way I was able to debug what caused the issue was by adding loggers, even for the apache http library. I don't remember exactly how I fixed :( Cheers -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
