a couple of things to check/look into
make sure your firewall is not preventing access to the server from another machine.
check and make sure the machine name and port in your settings are correct (localhost will only work when you are doing this all on the server)
Are you getting an error message?
We had trouble connecting to our server with On-Demand, but it was because we were trying to login with a password that was different than the one needed to access the QV desktop session on the server. In your Nprinting NSQ, you need to specify a user name and password for your source connection and this needs to be the same as the login to your server that will enable you to run QV on the server.
Another thing you can try is to open your QV app on your desktop and change to Web View. If you can make it work there On-Demand, than it should work on the Access Point. Note: we have found on the desktop version, that you have to change tabs or refresh to get the counter to change to 1. This does not do this behavior on the Access Point, only desktop version.
And, finally, never save your app in Webview. Always change back to normal view before saving.
Hope those suggestions help
