Without knowing more, the only thing I can think of is that some of the networking resources may be in a bad state. If you don't currently do this, it might be a good idea to force close the app (tap the recent icon, swipe MobileSheets off the screen) before starting a performance where you need to utilize the connect tablets feature. This will just ensure you have a clean slate. Can you try this on your home network and see if this has any impact on the ability to connect the tablets?
