Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble

[hotzenwalder]

Added the Atag One integration through HACS. When trying to add it to the dashboard, the configuration wizard fails to run. It says 'Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble'. Home Assistant is running on a Synology DS224+ in Docker. Other integrations works flawlessly, even the standard ATAG integration. I think it's trying to discover my ATAG One, which fails.

The error reads

Hi hotzenwalder,

Just released a new version that will fix the issue you have. (when it doesn't find a Atag One device on your local network) Please have a try with this release (v3.0.7). Please note that you need to enter the IP address manually after the discovery timeout. (30 secs)

Btw. not sure why your Atag One can not be discovered, but probably because you are on a vnet in Docker? Discovery broadcasts to other lan segments (vnets) are not send by default. Are you also having issues with the discovery of other devices? One thing to deal with this is to set the correct network adapter in the /config/network section? This should be the adapter that's in your local network.

It's working now. After a time-out I can manually add the IP address of the ATAG host. Hope this one will be more stable and not loose the connection every once and awhile.

My HA installation is installed in a Docker container on a seperate Docker network behind a reverse proxy (Traefik). Some devices can still be automatically detected (Philips Hue, Chromecast etc), but other devices need manual setup, like ATAG.

The Atag Discovery is using an UDP broadcast message which do not pass the proxy server. But indeed manually configuring an IP address should do as well.
