To add what Tom is saying, when I check your site in the Javascript
console, I see this error:

Uncaught DOMException: Failed to construct 'WebSocket': The URL
'ws://[mqtt://192.168.56.51]:9001/mqtt' is invalid.

The reason the site is not showing the real-time weather data is that the
local brower of your users needs to connect to the website on port 9001 to
get the MQTT topic data to present. Since you are posting your internal
server IP address, the internet user will not receive the information as
there is no way to route this correctly.

What I would do is change mqtt_websockets_host to
wetter.affolter.familyds.net and see if that works.

If it does not work, then the next best option is to set up Cloudflare to
host your domain name and route the websockets and internet traffic to your
local IP address at home. Cloudflare can help with the SSL Certificate
portion automatically. From there, you would use a reverse proxy (NGINX
Proxy Manager) to route the traffic correctly to your MQTT and WeeWX Web
Server instances. Please let me know if you have any other questions or if
you need instructions on how to do this.
