I've been having problems with my switches for the past month where they keep disconnecting. Actually, not disconnecting but refusing connections. I know they arent disconnected since I can still ping them and see them on the netwokr but trying to control them via the kasa app shows they are offline.
If I try and control them directly I get
"Error: read ECONNRESET"
I was also getting "Error: connect ECONNREFUSED" the other day.
The only way to bring them back is to physically press the reboot button.
This is happening to 3 devices at the right now.
