Can you try to create the file manually and access it via plain HTTP:

mkdir -p /var/www/.well-known/acme-challenge
echo 'this works' > /var/www/.well-known/acme-challenge/xclDxBCplrSQSNvv9klstrMm16SUjsf7ekMkTU6RldE
curl -IL 'http://mydomain.org/.well-known/acme-challenge/xclDxBCplrSQSNvv9klstrMm16SUjsf7ekMkTU6RldE'

and via browser.
