Jenkins / JENKINS-59181 The plain HTTP request was sent to HTTPS port Issue Type: Bug Assignee: Unassigned Components: core Created: 2019-09-02 10:59 Priority: Minor Reporter: Eugene Pliskin Our Jenkins server is located behind nginx server which forwards external HTTPS requests to Jenkins server by HTTP. Generally I can access Jenkins by HTTPS from outside our corporate network. However there are some pitfalls, probably related to some invalid redirection commands inside Jenkins server which inadvertently change URL from HTTPS to HTTP. For example: open Jenkins web interface with HTTPS open job configure page press Save button Then we get the following error message: 400 Bad Request The plain HTTP request was sent to HTTPS port nginx/1.16.1 This is because browser inadvertently switches from HTTPS to HTTP on Save button.   Add Comment

Change By: Eugene Pliskin Our Jenkins server is located behind nginx server which forwards external HTTPS requests from HTTPS port 10443 to Jenkins server by HTTP port 8090 . Generally I can access Jenkins by HTTPS from outside our corporate network. However there are some pitfalls, probably related to some invalid redirection commands inside Jenkins server which inadvertently change browser URL scheme from HTTPS to HTTP. For example: * open Jenkins web interface with at HTTPS port 10443 * open job configure page * press Save button

Then we get the following error message:

Almost certainly a bad reverse proxy configuration, https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+Nginx explains how to do it.
