Issues with Schlage Lock, currently failed node

I had a hard time adding my Schlage Lock and finally got it working. It worked for about 2 weeks.

Now it is reporting as a failed node.

What should I try to debug this?

Update: Current status is the lock is back online with no changes. Not sure why it was failing. I tested and the lock sometimes works when issued a lock or unlock command and sometimes doesn’t. I can’t figure out how to debug why it sometimes doesn’t work.
