ClickOnce

I have a ClickOnce deployment. Works well, and have been using it for many years. However, once in a while the deployment server either stops working or is unavailable. When this happens ClickOnce gets stuck and the application does not go on to execute. The issue as I see it is that ClickOnce checks the deployment server for a new release of the application prior to the application starting. Problem with that is if the deployment server is not responding or has gone off line how does click once decide to go on to run the application. Or more accurately, how can I modify click once to bypass the deployment server and run the application if the deployment server does not respond after say 15 seconds.
I have been looking at Madge to see if there is a way, but If I use Madge I would have to manually deploy the application to the application server.

What I have tried:

Microsoft and the Microsoft forums. No success there.
