Endpoint with name hassio_observer already exists in network hassio

I’m troubleshooting an issue with my Home Assistant server running on a Raspberry Pi 3B+ crashing on a regular basis. I’m not sure if it’s related but I’m noticing this error in the logs every few minutes (see full details below) and I’m unable to access the new observer page

I was able to install the Portainer addon and see that the Observer container is indeed not running and won’t start due to this error. I’ve tried removing the image and reinstalling the container (sorry not a docker person so I’m not sure I’m using the right terminology here) but to no avail.

Any help here would be greatly appreciated!

Well I’m glad I’m not the only one here, this issue has been driving me nuts. Anyone know how to get this seen by the developers?

Hey all, the latest supervisor update seems to have resolved this issue for me for now!

EDIT: I maybe spoke too soon, I’m still getting some observer errors, albeit different ones, and my server has crashed multiple times today.

Yup - Same for me…

Supervisor 2020.10.0
Hassio 0.117

Rpi3B+ running HA and Supervisor on Docker

Did the same with one of my other plugins - DuckDNS.

+1 had been happening since 116.4 on my installation.

I’ve got irregular crashes as well (where my zigbee2mqtt devices become inaccessible), a restart fixes it.

Same issue here… Not crashing, but repeating the error over and over in the Supervisor Log.

Operating System
Ubuntu 20.04.1 LTS
Docker version
19.03.6

I had the same problem with my installation. After doing some searching I came accros some suggestions that this might be related to some bug in Docker (https://github.com/sabeechen/hassio-google-drive-backup/issues/89)

Long story short; I rebooted my Pi3+ and the problem was solved.

me too, do you solve?

same issue, RPi3 and Hassio 0.107.4

Same issue for my installation:

RPi 3b+
Hassio 0.107.5
Supervisor 2020.11.0

Maybe we’ve to open an issue on github?

I already did: Endpoint with name hassio_observer already exists in network hassio · Issue #18 · home-assistant/plugin-observer (github.com)

Long story short; I rebooted my Pi3+ and the problem was solved.

Same for me… Try to click “Reboot” from Supervisor (not restart from Settings!) the Rpi and now I don’t have any error! :+1:

Restarting the RPi solves the problem temporarily. It comes up again after some time.

I don’t know how much time has to pass but for now (more than 24 hours, I speak softly!) the problem has not occurred again even after the update to HassOS 4.16 :crossed_fingers:
