Networking and servers • Re: ssh: connect to host 10.0.0.234 port 22: Host is down

Of course
Apologies - wood and trees !

Yesterday whilst creating a new clean install of Pi OS, I added logging of each sensors' full SQL to a test table with auto extry date time. to see if there was any significant time it went down / stopped recording.

This morning (still up) whilst examining the test table via SSH and getting results returned the screen froze.

SSH from another screen returned
ssh: connect to host 10.0.0.234 port 22: Host is down

my thoughts are that it not inactivity now that is causing the CM4 to sleep, but something else.
HARDWARE
=========
CM4 - 8 gb new last November
Raspberry Pi IO board for the CM4
Waveshare metal case
Raspberry Pi antenna

Temperature never rises above 30 deg C -as it is in a cool basement with an expensive MESH satellite for the WiFi and one Arduino opposite

CONNECTED
==========
level shifter 3.3 to 5.0 volts connected the right way round
GND to GND
5.0v to 5.0V
3,3v to 3.3v
TRIG and ECHO connected to WiringPi pin 4 and 5

but not used actively till I get the main system sorted.
SO will disconnect completely and re-test.

Power off and back on again and can connect, but performance is laggy
