Creating only subdomain cert with certbot

Help
#1

Hello,
I'm trying to get cert for my subdomain. I can create file with data listed above and wget or curl it.
But certbot is trying to check main domain where i don't have access to dns zone or ftp account.
Is that a bug or proper action?

My domain is: bip.gminawarta.pl

I ran this command: certbot certonly --manual -d bip.gminawarta.pl

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator manual, Installer None
Starting new HTTPS connection (1): acme-v02.api.letsencrypt.org
Requesting a certificate for bip.gminawarta.pl
Performing the following challenges:
http-01 challenge for bip.gminawarta.pl

Create a file containing just this data:

PszvxKT7STuqDPRxan_mOw3ereGNdTTlm2sDyn9jzw8.a_ApuyETPuMBtZ2ZGAS-_3jfYu_mzFgQ4L6dvCK90aE

And make it available on your web server at this URL:

http://bip.gminawarta.pl/.well-known/acme-challenge/PszvxKT7STuqDPRxan_mOw3ereGNdTTlm2sDyn9jzw8

This looks to me like an IPv6 issue. Your domain's IPv4 address responds with the Apache server, but its IPv6 address responds with a server running IdeaWebServer.

You'll want to make sure that both your IPv4 and IPv6 addresses point to your Apache server. If your Apache server doesn't have an IPv6 address, you'll want to remove the domain's AAAA DNS record.

Now only the IPv4 address is returned by DNS, and the IPv4 service shows:
Server: IdeaWebServer/2.0.5

Is this the correct IP for your system?:

Name:    gminawarta.pl
Address:  89.161.193.129
