I saw on another similar reported error on this site that you suggested manually creating /.well-known/acme-challenge/test.txt and seeing if you could browse too it. I ran that test and I was able to browse to test.txt

Hi @s15199d

@s15199d

/.well-known/acme-challenge/test.txt

check it with the file (file name 1234). Because the validation file has no extension.

With Windows, there is a mimetype required.

Unrelated to this issue, this website/domain has been transferred to a new owner. So, the issue is no longer relevant. @JuergenAuer thank you for your response!
