One of the new features in Orion is the Deployment Health site - shout out: Who Watches the Watchmen? The Orion Health Page!
When I would browse to Settings - All Settings - HA Deployment Summary
I could see my Orion server under the Servers Tab
Clicking on the Deployment Health or Updates Available Tab would bring up a short blank page
I tried all 3 major browsers with same results
I then tried to browse the site over HTTPS
BINGO!
Now I am able to see the content...
I'm unsure why this would only load over 443 and not 80, but it seems to do the trick for me.. and honestly we should all be browsing over a secure channel.
I hope someone else can find this post helpful.
