Jenkins after HTTPS reverse proxy keeps on redirecting to HTTP

Question

We have set up Jenkins behind an Apache reverse server with HTTPS. Although the default Jenkins URL is set to https://... in Jenkins and links on the GUI are working fine, all redirects ("302 Found") are pointing to HTTP, e.g. here: I could not find any existing thread on this here. Is there maybe some setting we might still be missing?

Addendum: This is the reverse proxy configuration we are using:

<VirtualHost _default_:8443>
SSLEngine On
SSLCertificateFile "C:/Portable/laragon/etc/ssl/abc-pub.pem"
SSLCertificateKeyFile "C:/Portable/laragon/etc/ssl/abc.pem"
<Directory "C:/Portable/laragon/www/">
    AllowOverride All
</Directory>
https://wiki.jenkins.io/display/jenkins/running+jenkins+behind+apache
ProxyPass         /jenkins  http://localhost:8080/jenkins nocanon
ProxyPassReverse  /jenkins  http://localhost:8080/jenkins
ProxyRequests     Off
AllowEncodedSlashes NoDecode
Local reverse proxy authorization override
Most unix distribution deny proxy by default (ie /etc/apache2/mods-enabled/proxy.conf in Ubuntu)
<Proxy *>
  Order deny,allow
  Allow from all
</Proxy>

@NicoHaase Thanks, I have added the Apache reverse proxy configuration (in text form :-) and asked the moderators to move to serverfault. — Robert, Mar 02 '22 at 13:19

I was able to resolve the issue by adding the following statements to the Apache reverse proxy virtual host configuration:

RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"

This does not solve the Jenkins issue but works around by rewriting HTTP requests as HTTPS.

Configure the proper URL in Jenkins. See https://serverfault.com/questions/931485/jenkins-behind-nginx-reverse-proxy-in-subdirectory/931486#931486 – Gerald Schneider Mar 02 '22 at 17:49

I wonder how can I set it up for an AWS ALB – Alex Weitz Apr 26 '22 at 08:30

You can try setting Manage Jenkins > Configure System -> Jenkins Location - Jenkins URL to the actual url of your jenkins.
