Server randomly changes URLs from HTTPS to HTTP

Added by Steffen Hoesel about 8 years ago

Hey Guys,

we have just deployed the OpenProject Server Version 6.0.3 on Ubuntu 14.04.5 LTS. It has a Certificate issued by our internal CA and it is running with HTTPS only. We’ve registered an internal A-Record on our DNS-Server which is resolved to its IP. So far so good. Most computers in our internal Network can connect to the server and work with OpenProject without an issue.

However … some Computers have trouble. When navigating to a Project and clicking on “Timeplans” (i dont know the correct english translation right now) or navigating back to their Homepage their browsers change the URL from “https://” to “http://”. And this leads to a timeout because HTTP is disabled. I thought its a cache problem with the browser but after clearing the Cache the problem still persists. And a completely new PC for a new employee has the same problems now. We are all using Firefox ESR; a package deployed by WSUS so the Browser is the same on all Computers.

Additionally we also forced an HTTPS Rewrite in the .htaccess File from the Apache Server after that error first occured. But this doesnt solve the problem.

Do you know what that is? Do you have any Idea why the URLs are replaced at certain points? And how to fix that?

Thanks for your help in advance
Steffen
