i'm getting totally nuts right now with our new OpenVPN AS and the Connect Client. Maybe there is someone here who can help me

I've installed a new OpenVPN AS on an Ubuntu Linux. When I install the Connect Client over the website everything works fine. But we have to deploy the msi to many computers without knowing the passwords of the user. So wie deploy the msi over our software deployings system.
The msi installs correctly. But there are no server defined, which I can connect to. If I wait for a couple of minutes this sometimes the COnnect to appears and then everythings is working as expected. Sometimes the Connect To disappears somehow. But I just don't get, when the Connect to is shown and in which cases it will not show.
Can anbody please clear me up, wi this happens? And what I can do to workaround it?
Thanks
Michael
