Failed Validation Limit

Help

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: app-cn.sibros.tech

I ran this command: sudo certbot certonly --manual -d app-cn.sibros.tech

It produced this output: Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:
Domain: app-cn.sibros.tech
Type: dns
Detail: DNS problem: NXDOMAIN looking up A for app-cn.sibros.tech - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for app-cn.sibros.tech - check that a DNS record exists for this domain

Hint: The Certificate Authority failed to verify the manually created challenge files. Ensure that you created these in the correct location.

Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

Did you read that?
Did you click the link?
It explains what the rate limits are and how they are enforced.

If it fails and fails and fails, trying again without making any change will likely just produce another failure.

You should do such testing in the LE testing environment.
You should be prepared to make change(s) OR you may remain in the same place.
If you don't know what to change, start with the error:

You mention:

But you don't mention what was entered/chosen after that.

Try adding --preferred-challenges=dns to your command to use DNS Challenge.

sudo certbot certonly --manual -d app-cn.sibros.tech --preferred-challenges=dns

You may be in luck:

sibros.tech nameserver = ns-cloud-b1.googledomains.com
sibros.tech nameserver = ns-cloud-b2.googledomains.com
sibros.tech nameserver = ns-cloud-b3.googledomains.com
sibros.tech nameserver = ns-cloud-b4.googledomains.com

You may be able to automate the DNS-01 authentication process.
