My domain is: iskalar.com
certbot 0.31.0

I ran this command:

sudo certbot certonly --manual -d *.iskalar.com -d iskalar.com --agree-tos --no-bootstrap --manual-public-ip-logging-ok --preferred-challenges dns-01 --server https://acme-v02.api.letsencrypt.org/directory

Output:

Please deploy a DNS TXT record under the name
_acme-challenge.iskalar.com with the following value:

VF2OMqNtJBL8K2uOFx_gjSDdVioQeIwoCMcqiN3-qEQ

Before continuing, verify the record is deployed.
(This must be set up in addition to the previous challenges; do not remove,
replace, or undo the previous challenge tasks yet. Note that you might be
asked to create multiple distinct TXT records with the same name. This is
permitted by DNS standards.)

Press Enter to Continue

Cleaning up challenges
Failed authorization procedure. iskalar.com (dns-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Incorrect TXT record “VF2OMqNtJBL8K2uOFx_gjSDdVioQeIwoCMcqiN3-qEQ” found at _acme-challenge.iskalar.com

*I deployed the DNS TXT value and hit enter. *

IMPORTANT NOTES:

The following errors were reported by the server:
Domain: iskalar.com
Type: unauthorized
Detail: Incorrect TXT record
“VF2OMqNtJBL8K2uOFx_gjSDdVioQeIwoCMcqiN3-qEQ” found at
_acme-challenge.iskalar.com

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.

Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.

*NSlookup give the same value. *

$ nslookup -q=txt _acme-challenge.iskalar.com ns1.digitalocean.com
Server: ns1.digitalocean.com
Address: 173.245.58.51#53

_acme-challenge.iskalar.com text = “VF2OMqNtJBL8K2uOFx_gjSDdVioQeIwoCMcqiN3-qEQ”

What should I do to make it work.
Can i re run the command. Do I need to delete any files. before re running the command?
