I went through the steps described here and - after contacting my provider procredo - ended up with the following situation:
Whatever I looked at n the dashboard showed me that “everything was OK” but unfortunately, it wasn’t. When I tried to call up our page with “swing-o-matic.de” the result is shown in the lower part of the above image.:
The “https://” at the beginning was added automatically, but unfortunately the connection to our page was not made.
To enable our users to contact our page again I “paused” the cloudflare-service for the time being. So, now you can connect to
swing-o-matic.de without problems. What do I still have to do to make the cloudflare service work?!?
