Home Assistant 2024.8.x - Failed Docker connect: tcp://A.B.C.D:2375/version

[ualex73]

Home Assistant seem to have made internal changes with aiohttp and it will not accept remote URLs like:
tcp://192.168.1.1:2376

But the format is changed to (replace tcp with http):
http://192.168.1.1:2376

NOTE - this should make it work again with not-TLS connections, no testing has been done (yet) with TLS connections.

This also seems to block unix socket calls as well.

I did not test that one yet, but it seems Home Assistent 2024.8 seem to break it all :-(
Only quick workaround is to switch to URL.

BTW: it has been raised with the aiohttp team:
aio-libs/aiohttp#8600

Affected as well. Solution for me was to modify docker daemon to listen on a localhost port (my Home Assistant container uses the host network), restart docker daemon, then configure the url key in monitor_docker config. YMMV.

https://docs.docker.com/config/daemon/remote-access/

[andrew~]$ cat /etc/docker/daemon.json 
{
  "hosts": ["unix:///var/run/docker.sock", "tcp://127.0.0.1:2375"]
}

configuration.yaml:

monitor_docker:
  url: "http://localhost:2375"

The workaround is not working for me either (sudo systemctl edit docker.service).
Have Docker on Debian Linux and HA is in Docker w/ nginxproxymanager (not host network).
Will wait for a future update to hopefully fix it.

Is this solved with aiohttp 3.10.2 ?

[bdraco]

docker exec -it homeassistant /bin/bash
pip3 install --upgrade aiohttp

restart

Is this solved with aiohttp 3.10.2 ?

I've confirmed it does fix it on my container.

[bdraco]

Thanks for confirming

[ualex73]

HA 2024.8.1 is out, so please upgrade to that one.

Ok, let's leave this issue open for a few days for other people to read it, afterwards we will close it.

You could also pin the issue 👍
