If you choose the http challenge type, what are the details of passing the challenge?
I’m looking at the certbot source and I see a test in challenges.py:
http://example.com/.well-known/acme-challenge/
So if I am requesting a cert for the domain example.com, it will try and make a http get request for:
http://example.com/.well-known/acme-challenge/
What does it expect as the response?
Here's a fairly detailed response I posted to this same question in the past: What's the file that http-01 challenge requires at challenge? - #2 by cpu
You might find @schoen's condensed reply more accessible: What's the file that http-01 challenge requires at challenge? - #3 by schoen He writes for humans a lot better than I do!
For what it's worth, it doesn't make a request for the exact URI http://example.com/.well-known/acme-challenge/, it makes a request for a file in that directory, like http://example.com/.well-known/acme-challenge/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. (Let's Encrypt tells your ACME client what the file name is.)
Thanks.
BTW this might be ironic but your website in your profile binaryparadox.net has a cert error!
Actually, I think that is my companies internal firewall sorry!
You had me worried for a second!
