Home Assistant not accessible

I have 0.92.2 running on a raspberry pi and every n days, I cannot connect via ssh or the web page. I can ping the device but nothing else. The only way out is to power off / on the device.

Is it a bug, configuration issue or other ?

Do you have camera streaming enabled?

No I don’t stream any video. I do have a z-wave controller and a few z-wave devices, a few automation scripts. Not much more.

When you reboot the device you can access it?
I used to have some wifi issues back when i started and kept loosing conection.
I ended up using ethernet connection to my RPi and set up an automation to rebstart HA server every morning.

Yes, access is possible after a power off / power on sequence.
