When opening NetDocs within a matter, the client gets an error that reads "login.microsoftonline.com refused to connect."
Whenever this error occurs, typically there is some sort of blocker that is preventing NetDocs from showing up within Centerbase, usually coming from a DNS Resolver. An example of this is Microsoft Azure.
To get NetDocs to show up, go into the DNS Resolver and see if there is an option to Deny X-Frame. If this option is turned on, that is preventing the website from showing up in Centerbase. We will need to disable it in order to continue through Centerbase.
