You can't have "no default vhost", as the first <VirtualHost> block will automatically be the default.

Ah, thanks, good to know.

The result from https://check-your-website.server-daten.de/?q=sonvpn.myddns.rocks helped me to realize that the WD NAS, which I enabled for remote management many years ago, was the culprit. Once I disabled it, everything works fine now.

So it was a completely different instance / machine that had answered.

Happy to read you have found that problem
