The problem is, randomly (every 2-3 weeks) the “server” goes down. Then the raspberry respond to a ping and if I go to the ip without a port then the Congratulation from the nginx proxy server shows up but the webinterface doesent load when I add the port. A connection with ssh also doesen’t work.
For the onlinecontrolling I use uptimerobot this said today that home assistant goes off at 15:22 (3:22pm). Then there is only 1 solution, unplug the power and plug it in again. At this time I saved the home-assistant.log.1

This log says nothing special or anything becaus the last messange was about 1 hour ago.

How can I find the problem?

Watch your cpu and ram usage.

This looks normal

I had a similar problem. My solution was to replace the power supply. Now it is really stable again.

thanks, but for the pi it’s the original 5,1v 3a power supply
I try now another 3a powersupply maybe it work’s better.
