Recently saw an error message when trying to disable the connection server via the admin UI, which reads:
Failed to update the Connection Server.

So it turns out from Ronald that unless you have both the SSL gateway and Blast gateway either checked OR unchecked the disable button won’t work. Not sure in what versions of View this problem exists, because I’m pretty much only disabling connection servers when there’s a problem or when doing an upgrade. Either it’s a bug, or a KB needs to be built for this error dialog. Until then, I hope this post finds you well fellow Horizon administrators!
