Browser shows page source when accessing JBoss ON UI login page through reverse proxy

Solution Verified - Updated -

Issue

  • I did an upgrade in our test environment from JON 3.2 to JON 3.3.1. But after the upgrade I run into a big problem. After the server "load page" is done i will come to a HTML page. It looks like JON doesn't read the HTML code and present it as it should.
  • JBoss ON 3.3 login page is loaded as a source instead of html;
  • Browser shows page source when accessing JBoss ON UI login page through reverse proxy
  • When accessing JBoss ON login page through reverse proxy, my browser shows:

  • reverse proxy in front of jon shows html source instead of genreating the page.
  • We installed jon to listen to localhost and put a apache in front of it which acts as a reverse proxy. When we access the url we get the source code printed instead of generating the actual login page.
