I need to prove that I own the domain that will be covered by this SSL certificate so I need to create a file with a specific name and containing specific content, but I can't seem to get it right.
I'm being asked for the following
Make sure your web server displays the following content at http://www.domain.com/.well-known/acme-challenge/7xLLYjA7YGAvkCaASuJQl6PE8nHYFh6TBvyMRD3 before continuing:
[Long String That I'm Being Asked To Display Here]
So through Filezilia where all of my site files are, I made a separate directory for the following with acme-challenge in the .well-known directory and so on
.well-known
acme-challenge
7xLLYjA7YGAvkCaASuJQl6PE8nHYFh6TBvyMRD3
Then in the directory 7xLLYjA7YGAvkCaASuJQl6PE8nHYFh6TBvyMRD3 I created a file with the title of the [Long String That I'm Being Asked To Display] and entered it as the content of the text file as well.
But when I go to enter and get LetsEncrypt to check the authentication, I get the following message
Self-verify of challenge failed.
Am I doing this completely wrong or am I on the right track here?
