Everything was working pretty well until I ran NCM installer and then the NCM Integration utility. Now I get
"Service Unavailable
HTTP Error 503. The service is unavailable."
..when I try to go to Orion. Any help would be appreciated.
A reboot of the server appears to have brought things back. This was not included in the installation instructions for integration.
Typically you don't need a reboot. Sometimes it will ask for a reboot though if a file is locked when trying to install or upgrade though
