This sounds as if you have loaded "mod_md" and it has taken over the /.well-known/acme-challenge folder. This was a bug in that module which has been fixed in subsequent releases. If you do not use mod_md, the easiest remedy is to not load it into your server. If you want to use mod_md together with other Lets Encrypt clients such as certbot, you need to upgrade to a recent Apache httpd version or get the module from github and compile it yourself.

I went to renew all of my certificates using an automated script that worked fine 3 months ago on the last refresh. It failed on every domain saying the challenge file was not found. I put a test.html file in /.well-known/acme-challenge folder, and tried to access it with a browser, and it gave me a 404. After moving the test.html file around into other folders, it was found correctly in every folder except acme-challenge. [...] > > what's in the Apache logs?
