No Valid IP Addresses found

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
deltatuf.tk
I ran this command:
certbot certonly --standalone
It produced this output:

My web server is (include version):
apache 2.4.46
The operating system my web server runs on is (include version):
Windows 10 19042 20H2
My hosting provider, if applicable, is:
freenom.com
I can login to a root shell on my machine (yes or no, or I don't know):
i dont know unless command prompt counts
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.12.0

Hi @DeltaTUF, and welcome to the LE community forum :slight_smile:

There is no IP found for that name in global DNS.
[the "www" does have an IP]

Standalone implies using HTTP authentication.
For HTTP authentication, you must have a valid IP and TCP port 80 must be open through the firewalls and allowed to reach the system that is running certbot.

hi there, thank you for your reply, so I tried that and got this response

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.

i also have an mc server which uses tcpshield and is occupied by the CNAME www.

the IP in that response 51.161.99.33 comes back to an OVH in canada

how should i come around this

If the IP returned by the "www" is NOT the IP being used by the system where you are trying to get a cert, then HTTP authentication will fail.
That is like me trying to get a cert for Google.com, I don't have an IP that name resolves to - so I can't get a cert for it.

Is there a name that points to the IP where your server is at?

how would i find this out

i added a dns record for the IP to be pointed to under A
and was returned with this result

←[0m - The following errors were reported by the server:

Domain: www.deltatuf.tk
Type: dns
Detail: DNS problem: NXDOMAIN looking up A for www.deltatuf.tk -
check that a DNS record exists for this domain

Global DNS can't resolve "deltatuf.tk" nor "www.deltatuf.tk".

You can use the CLI tool dig to validate what IP public DNS servers are seeing for your domain:

e.g:

➜ dig @8.8.8.8 +noall +question +answer deltauf.tk www.deltauf.tk community.letsencrypt.org
;deltauf.tk.			IN	A
;www.deltauf.tk.			IN	A
;community.letsencrypt.org.	IN	A
community.letsencrypt.org. 15	IN	CNAME	letsencrypt.hosted-by-discourse.com.
letsencrypt.hosted-by-discourse.com. 15	IN A	64.62.250.111

As you can see the community forum has an IP address while deltauf.tk does not.
