I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

http + /.well-known/acme-challenge/random-filename doesn't answer.

Works with my browser.

Looks like there is a bot detection that doesn't work with that online check and with the Letsencrypt check.

-->> Find and remove that. May be your server, may be your hoster.
