Cannot connect to host version.home-assistant.io:443

#1

I currently have the problem that my home assistant cannot reach the home assistant versions page.

I have already read several posts, but with them the problem is that home assistant cannot update. With me the update card is not there at all?

This is my logging when i reload the HassIO supervisor:

20-02-09 19:49:17 INFO (MainThread) [hassio.updater] Fetch update data from https://version.home-assistant.io/stable.json
20-02-09 19:49:22 WARNING (MainThread) [hassio.updater] Can't fetch versions from https://version.home-assistant.io/stable.json: Cannot connect to host version.home-assistant.io:443 ssl:None [Try again]

When i open the link wich is provided in the logging then i see the JSON file.
What i’ve already done is restart home assistant completely. Also shutdown all addons.

I also deleted all backups to free up any space. But according to the system, only 6.4% has been used. I have a 64 GB card in it. So this should not be the problem either.

Maybe 1 of you has an answer for this.

Can't fetch versions

In addition to this, I also saw the following happen this morning.

I have the feeling that something is being blocked / blocked somewhere. I run Pi-hole on home assistant. Could this be the cause?

#3

I have the exact same problem.
It’s interesting, that I can curl https://version.home-assistant.io/stable.json successfully via ssh on my pi.
And I had this problem before. I solved it by manually downloading the latest update via cli.

But apparently I just solved it by enabling “Listen on all interfaces, permit all origins” in the Pi-Hole addon (under Settings -> DNS).

#4

I have no Pi-Hole installed, still I have issue in update.

Any idea ?

#5

So I did the following.
Logged in to my router and set the secondary DNS to 1.1.1.1. This worked for me. Now I’m getting al the updates so apparently Pi-Hole did blocked the updates.

Have you tried this instruction? → https://github.com/home-assistant/operating-system/blob/a592fc986610fac9dbaec96f514ee616c1a44d17/Documentation/network.md#static-ip

I was having an issue with the exact same symptoms and that instruction did help me.
