Is there a way to satisfy an ACME HTTP-01 certificate validation challenge with a power pages site, such one would have to do using Let's Encrypt? The DNS challenge is not an option, in my case, so it would have to be HTTP-01.
I have not made a lot of power pages yet, but I see that the page names can only include letters, numbers, and hyphens. At the end of the day, the challenge is really just "serve this one little file", but I don't think this platform will let you establish a URL path like "/.well-known/acme-challenge/" in front of the file's name.
Does power pages effectively make you have to pay for a TLS certificate, if you can't do the DNS validation?
