Make sure to follow https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+Nginx <https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+Nginx> if Nginx is configured as a a reverse proxy.

(If your Jenkins logs at the time you try to connect via CLI have errors that say something to the effect of “Full-duplex channel timeout” then I expect those settings to fix it.) > On Oct 26, 2017, at 5:18 PM, 'Tomasz Chmielewski' via Jenkins Users > <jenkinsci-users@googlegroups.com> wrote: > > Except... it doesn't seem to work. > > $ java -jar jenkins-cli.jar -s https://jenkins-url <https://jenkins-url/> > -auth user:pass help offline-node > $ echo $? > 255 > > In nginx log: > > 10.11.0.8 - user [26/Oct/2017:21:11:51 +0000] "GET / HTTP/1.1" 200 150393 "-" > "Java/1.8.0_131" > 10.11.0.8 - user [26/Oct/2017:21:11:52 +0000] "GET > /crumbIssuer/api/xml/?xpath=concat(//crumbRequestField,\x22:\x22,//crumb) > HTTP/1.1" 404 335 "-" "Java/1.8.0_131" > 10.11.0.8 - user [26/Oct/2017:21:12:07 +0000] "POST /cli?remoting=false > HTTP/1.1" 200 11 "-" "Java/1.8.0_131" > 10.11.0.8 - user [26/Oct/2017:21:12:07 +0000] "POST /cli?remoting=false > HTTP/1.1" 500 13912 "-" "Java/1.8.0_131" > > How do I debug this? > > > > On Friday, October 27, 2017 at 6:07:03 AM UTC+9, Tomasz Chmielewski wrote: > Got it, thanks: > > https://wiki.jenkins.io/display/JENKINS/Jenkins+CLI > <https://wiki.jenkins.io/display/JENKINS/Jenkins+CLI> > > On Friday, October 27, 2017 at 5:57:18 AM UTC+9, Robert Hales wrote: > You have to use the Jenkins CLI.
