Can't Connect to the Cloud

[next jay]

As seen in the image it says unable to reach. Through the FAQ I found that this indicates IPv6 issues. It doesn't make sense to me because:
A) IPv6 is disabled in my NAS
B) IPv6 is disabled in the docker container where I installed Home Assistant
C) IPv6 is disabled in the configuration.yaml file by adding
http:
server_host = 0.0.0.0

I want this fixed because I have devices that rely on the cloud, according to the Home Assistant software. One of these being my humidity and temperature reader.

This, by the way, is weird to me too because why pay for a cloud service when I have my private cloud; my NAS with over 20TB of storage. For external access? Not necessary, I can configure that myself too with port forwarding. But that's a different discussion.

Noteworthy info:

• NAS : DS423
• I use Glasswire, NordVPN on my Computer and also NextDNS (possibly I have installed NextDNS on Router level too but I am unsure).

Install script used for the container:

docker run -d --name=home_assistant \
-e TZ=Europe/Amsterdam \
-v /volume1/docker/homeassistant:/config \
--net=host \
--restart always \
homeassistant/home-assistant

Another interesting point that is perhaps related is that my Network Settings screen is completely black, as seen in the second image.

Any help would be highly appreciated.

Btw, I have a Tuya humidity and temperature controller... How can I view the data on a per-minute basis? 🤔

I have set it up in the smart life up to report every 1 minute.

You should be able to load your network settings in HA. I would focus on that first. Something is not right here.

It sounds more like an IPv4 issue

There’s no requirement to use the Nabu Casa cloud service. Home Assistant itself is a web server, and many people have been accessing it remotely long before Nabu Casa existed and still do. Nabu Casa simply provides an easier, convenient way to access your Home Assistant remotely without having to deal with things like opening ports. It also helps fund the full-time development of Home Assistant, which is otherwise a free, open-source, community-driven project. Hosting, time, development, organization, and community structure would likely be (more) chaotic without it

Ah okay, that makes sense, thanks.

In that case I don't need to resolve my network issue as the rest is fine.
