Could not issue a Let's Encrypt SSL/TLS certificate for sad-cray.10-1-0-4.plesk.page . Authorization for the domain failed.

That hostname resolves to the IP address 10.1.0.4 which cannot be used for the http-01 or tls-alpn-01 challenges. If you're using a private IP address, you can only use the dns-01 challenge to validate the hostname.

"How would I do that in Plesk", you might ask? No idea..

Thanks for the response, it was the conclusion I came to in regard to Plesk, no idea on how you do it

I do not know Plesk either but maybe try the Plesk forums?

Some starter ideas

Why are you using IP 10.1.0.4?
[even if you get a cert, no one (on the Internet) will be able to reach that IP]

Do you plan on serving any Internet clients?

What is the purpose of the cert?
