Top Navigation Links redirect to HTTP

LucasScharenbroich

So, a very strange situation ... I've installed Portal for ArcGIS several times and have never seen this behavior. When I click on the top navigation links I am getting redirected from the HTTPS protocol to HTTP.  The installation is very standard:

• Portal installed on a dedicated machine with its Identity store pointed to Active Directory.  Portal has not been reinstalled and the underlying machine name has not changed.
• A Web Adaptor is installed on a separate IIS web server on a separate machine.  Anonymous access is enables and a valid certificate is installed that was issued by AD CS.

Now, the strange behavior is that, whenever I click on the top navigation links, "My Content", "Groups", etc.  I am getting redirected to an HTTP url.  This behavior is consistent across browsers.  I've included screenshots from IE and Chrome.  Firefox behaves the same as Chrome.

Anyone know what is causing this problem and how it can be fixed?  I have restarted Portal and reviewed the "self" REST endpoint and looked at the page source, and I do not see any place where an explicit HTTP link is being set.  All of the navigation anchor tags appear to be relative URLs.

Thank you.

What happens when you put Portal into "Allow access to the portal through HTTPS only."

I believe without that setting, most pages that do not require HTTPS (such as login) will redirect to HTTP.

Perhaps the following will spark an idea:

I have had an issue with a problem that is sort of the reverse of this.

I was in Allow HTTPS only mode and turned it off.

Portal then would redirect to HTTP for most of the web pages but I kept getting an error that HTTPS was required.

In that situation, my IIS SSL settings were set to SSL Required.  I turned it off and was back to a mixed mode Portal that worked as expected.
