Hello, my node was working properly until… it wasn’t anymore. Tried to connect through SSH for a log with no success. So I took a picture of the monitor. Posted on the telegram group but no one could help me. I don’t know where to start diagnostic or what to do. Thank you for your support.
Do you have another RPi to do a test? Seems something bad with the RPi hardware.
Only change the RPi, keep same SD and SSD.
I don’t have 
Do a test with another system, flash a SD with Raspbian for example.
