Yesterday i upadate hassio to 90.0. Today i get error like on photo and now i can not select hassio in menu bar, so i can not update hassio to 90.1 (i do not know if this even will help in this problem)
I have same problem too. we create an issue on github
My log:
2019-03-21 16:04:48 ERROR (MainThread) [homeassistant.components.hassio.handler] Timeout on /supervisor/ping request 2019-03-21 16:04:48 ERROR (MainThread) [homeassistant.components.hassio] Not connected with Hass.io 2019-03-21 16:04:48 ERROR (MainThread) [homeassistant.setup] Setup failed for hassio: Component failed to initialize.
Same problem here too: I had to go back to 0.89.2
Isn’t 0.90.1 out for hassio? I upgraded Home Assistant last night.
How can I upgrade it? I have no hassio menu and SSH is disabled?
Do you have console access? I believe hassio has a cli command structure too.
You mean that i pulg keybord and HDMI directly to RPI?
Yes, that would work.
Assuming a HassOs image, at the login: prompt just type root
I think you just need to type homeassistant update Here is a reference page.
Yes: use “hassio supervisor update” from ssh console and you’ll install 0.90.1.
The problem is still here …

Now that I think about it, I think both supervisor & homeassistant parts need updating this time. I do not use Hassio.
Ok, i found the cause of the problem. If I add “device_tracker:” to the config, the system stops showing Hass.io.
Now, WHY device_tracker:?
