Issues with certbots ssl certificates

[AXE0928]

Hi, I'm not great at this so please bear with me. So I'm trying to make ssl certificates and host a MC server off of it. So I use the domain for a website if it is unable to be used for a website and a domain like this then I know my issue, but I believe you can use a subdomain so I don't think it's that. So I tried both my domain (rockymountainhosting.ca) and my subdomain (portal.rockymountainhosting.ca) but both resulted in errors which I could not figure out

I ran this command:

certbot certonly -d rockymountainhosting.ca
&
certbot certonly -d portal.rockymountainhosting.ca

It produced this output:

The top is from the domain and the bottom is from the subdomain

I'm running on ubuntu 20.04 if you need any additional info ask and I'll try to find it.
Thank you all in advance

Hi @AXE0928

@AXE0928

certbot certonly -d rockymountainhosting.ca

that domain is google-hosted - see https://check-your-website.server-daten.de/?q=rockymountainhosting.ca

Host	Type	IP-Address	is auth.	∑ Queries	∑ Timeout
rockymountainhosting.ca	A	216.239.32.21 Montreal/Quebec/Canada (CA) - Google LLC Hostname: any-in-2015.1e100.net	yes

and a lot of other ip addresses.

So only Google can install a certificate.

And there is already a certificate, https works.

CN=rockymountainhosting.ca
	16.12.2020
	16.03.2021
expires in 82 days	rockymountainhosting.ca - 1 entry

same with the www version.

So you don't need a Letsencrypt certificate. And it may be impossible to create one via http validation, because Google manages that website.

Your subdomain does't have an ip address, so you can't use http validation.
