Happy to see that it works.
I don't know. Because my tool sees only a blocking firewall ( https://check-your-website.server-daten.de/?q=ggc.world ):

Perhaps you should fix that, so you can use http-01 validation, so you don't need --manual.
/.well-known/acme-challenge/unknown-file has the same blocking answer, but that must answer if you want to use http-01 validation.
