Last thursday I got a notification that my HomeAssistant disconnected. I could not get the UI to load up, always timed out. I played around with several different things before giving up and repaving with HAOS again and restoring a backup from 2 days before the random crash. No luck, looked like it worked and then the UI stopped responding again right away.
RaspberryPi 5 with an external SSD via usb, been running HomeAssistant for over a year without any issues until now.
I can connect via SSH, and if I run ha core restart everything will come up for about a minute, and then the UI becomes unresponsive again. I've commented out almost all of my automations. I've unplugged my z-wave and zigbee devices from the pi. Though as you will see there are still some errors in the core logs.
Looking for some help in how to track down what is suddenly taking my system down. The ssh stays connected consistently, so doesn't feel like a problem with the hardware.
