Where do I need to place "/.well-known/acme-challenge"?

I want to make certbot working (to get free ssl) but I need to create “acme-challenge” folder inside the “.well-known” folder. Nothing works so far, I tried many combinations but it always ends with Invalid Response from certbot. I’m using windows and manual method.

By the way, is this even possible to have certbot working on infinityfree? Any help is appreciated.

Why not just use InfinityFree SSL Tool?


Your most likely get an invalid response because of this:


Alright I guess it will work now. I used SSL tool and added CNAME. Now I have to wait until DNS finds it.
