The client lacks sufficient authorization - 404

Hi!,
Thanks for your response.

Yes, this URL is the one where it should be.
My project is under “/home/www/amicare” and DocumentRoot has been defined as “/home/www/amicare” in my /etc/httpd/conf/httpd.conf
I’ve got a .htaccess where I defined: Options +FollowSymlinks +Indexes.
And I made a "chmod -R 777 /home/www/amicare/.well-known"
When I am surfing from Internet to http://MyServer/.well-known/acme-challenge, I get:
Index of /.well-known/acme-challenge

Name	Last modified	Size	Description

Parent Directory -
Apache/2.2.15 (Red Hat) Server at MyServer Port 80

But I can’t get a cert from LE.

Thanks for your help
