My Pi stopped responding yesterday. It normally serves an html page with sensor data using apache. When I browsed to the IP I got 403. When I tried to SSH I got
kex_exchange_identification: read: Connection reset by peer
Connection reset by 192.168.1.11 port 22
I cycled the power and it is back and appears to be functioning normally. The Python script collecting data from a sensor and logging it every 5 minutes using cron stopped about 36 hrs ago so it seems like a full system crash. Can anyone suggest where I should look for logs on RasPiOS Buster that might indicate what went wrong, or how I can get the Pi to create such logs, if they're not enabled by default?
