Ring Base Station lost wifi connection

My Ring base station started to complain that it has lost internet connection. Reconnect from the app didn't help. I pushed reset button on the device and it fixes the problem. I observed this problem 4-5 times last week. I have never seen it before (using Ring for a year now). Other devices don't have any problems with wifi. Wifi signal is very strong at that spot. Firmware is up-to-date. How can I open a ticket with Ring to diagnose the issue? Thanks.
