Connect call failed

Hi,
I'm facing an issue with the latest HA version, before opening a ticket to Hella, can you help me?

Questo errore ha avuto origine da un'integrazione personalizzata.

this is interesting. i am running the same versions and it's working fine.

could you try to reach your ONYX locally from your machine like:
curl -k https://192.168.3.253/api/versions (see https://github.com/hella-info/onyx_api?tab=readme-ov-file#examples-1)
if this doesn't work, please double-check your IP address and possibly network. if it still doesn't work, it's probably a case for Hella themselves.

if this works, the issue might be within your home-assistant instance itself. so let's run above command again from directly on (1) the HA server and (2) from directly within the container.

• if (1) doesn't work, please check the routing and network configuration of your HA server.
• if (1) works but (2) doesn't then there might be an overlap with the Docker network CIDR or a routing problem from the container to your network. In that case, I'd check the Docker configuration first and also check what IP addresses are reachable from within the container and which ones are not.
• if (1) and (2) works, let me know because that's gonna be very interesting as i wouldn't be able see why the integration can't reach the ONYX device then...

I tried it after a manual restart and everything worked fine, but after a few hours it went down again.
The strange thing is that I can access it from their ONOX Center app, while even from the UniFi console it appears disconnected from the WiFi, as if it had been stressed and given up 😅
