"Unexpected Error" - Why does this error keep happening?

Every few days or so, when we try to use the App to arm or disarm, we get a message that says:

"Unexpected error"   "Contact Customer Service"

Here is what the error message looks like:

If we choose "cancel", usually the function (arm or disarm) works.  But there is a delay and sometimes no Push message is received and sometimes the timeline doesn't update to show armed or disarmed.  So then we have to do it again -- arm, then disarm and it goes through.

I have tried resetting my base station (removing the batteries and power cord) and also changed the WiFi setup for the base station to be all by itself on our guest WiFi network (2.4).  Connectivity is super strong on our system - there are no WiFi or sensor issues.  And we generally have no other issues or problems with our 10 devices/sensors. 

So how do we stop this error from happening?  It is disconcerting and concerning, particularly if trying to disarm while the countdown is underway before the alarm goes off.

Do I need a new base station?  I noticed from the information on the bottom of my base station that it is from August 2023 (but I purchased it in August 2024).

Thanks!
