Keypads and Dimmer switches no longer working

This morning, two of my keypads and dimmer switches stopped working. They worked fine the night before and I have other keypads and dimmer switches that work fine. The ones that don't work are isolated to a certain area. I checked my breaker box and it's fine. Any ideas on how to troubleshoot would be much appreciated.

TIA,

Dan

Is there an auxiliary repeater? Usually when I see this, it means the Aux has been unplugged.

In the software, there is a diagnostic tool under tools. Find the main repeater and run the tool, it should show that it isn't communicating.
