I’m a liitle helpless. My Request Certificate process fails. Tests were successfull.
Even the URL http://app.reservierungsplaner.de/.well-known/acme-challenge/XQSR-fNJlkzrm5NlYvlPudltMjekp4lkubuuZT5KBXc works while the process runs - seems that the HTTP Challenge Server works fine. A browser from outside shows
But the domain validation failed.
Any ideas what’s missing?
