Timeout and incomplete answer checking the validation file

Hi @Reals

I've moved your question to a new topic, makes things easier.

There is an additional, curious error, different from the error of Timeout during connect (likely firewall problem) on 8.43.85.0/24 - never seen earlier.

Checking your validation file

http://codes.mcdelivery.md/.well-known/acme-challenge/as44OoFsaJkeiSOdGqQPwtIjgi7tp2-12YMFSI17GNc

with my browser: The content:

as44OoFsaJkeiSOdGqQPwtIjgi7tp2-12YMFSI17GNc

That's an incomplete validation file. The validation file must include:

  • the filename ( as44OoFsaJkeiSOdGqQPwtIjgi7tp2-12YMFSI17GNc is the filename)
  • a dot "."
  • the hash of the public key, that's missing.

So a correct challenge file must have a content like

_auTTDlrpaGVcbpT3zVaNa0w_v2_7YmcqygiHFCO9yw.yCch0mVZpEbB8u8Y4kPLwLUuccDBa3JMMSs08-s3_k0

There must be a blocking instance that filtered something: Partial blocked (timeout), partial interrupted.

Perhaps a bot detection that doesn't work with Letsencrypt, perhaps a script of your hoster.
