| I am on 2.190.2 and had the same issue. We are also behind an Apache reverse proxy, and we had mismatching slashes in the proxypass directive: We had ProxyPass / http://127.0.0.1:8080/ ProxyPassReverse / https://MYURL instead of ProxyPass / http://127.0.0.1:8080/ ProxyPassReverse / https://MYURL/ A sidenote: It is not possible to remove the slash from the URL in Jenkins. I can change the URL manually in jenkins.model.JenkinsLocationConfiguration.xml, but whenever I try to remove the slash from the "Jenkins URL" field in the web configurator, it reappears. |
