Cannot access Supervisor or config.yaml - Client error on api app/entrypoint.js request Cannot connect to host

Configuration

Hi all,
since one week I cannot access the Supervisor, File editor (to edit .yaml files), or terminal. I did not change anything, but the following errors appeared in my log:

HA errors
HA errors994×353 31.5 KB

Automations are working fine, and I can access the settings section.
Who can help me? Seems there is not much I can do without access to the configuration or terminal…

Hi XxCabbyoO,

no fix yet, the topics on the internet point to different solutions. Most online topics are closed, stating each problem has its own specific solution. That is why I posted it on this forum.
One thing I read on the forums is that a hard reset (pulling the plug) could help, but I am hesistant to do that since this could ruin my SD card.
I am on a RPi3 by the way, so no way to access it now. Possible the samba plugin still works in order to backup, but have not tried that yet.
Recently one of my smart lights running on Zigbee also disconnected, and as I cannot access my configuration I cannot re-pair it again.

However, will wait for some days, hopefully someone comes with a specific solution. I do not like errors after nothing has changed by the user…

So a temporary fix like a hard reset will not take away my worries, as the problem could appear again. I hope there will be a definite fix for this. I believe there are many peoping having similar problems.

a hard reset has solved the problem for me, let’s see if the bug comes back.

Good to hear. Did it auto-update the supervisor version? What version do you have now?

Hard reset solved the issue. Hopefully this problem will not appear again in the future.
