Issue with Certificate renewal

Hello,

I am having issues with certificate renewal:
*SniCertificate::CertificateNonvalidError: Unable to verify challenge for .aitanalmagor.com: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.aitanalmagor.com - check that a DNS record exists for this domain

My Netlify site name is : chimerical-bavarois-a9c7b9.netlify.app

please assist,
Mayan

It appears aitanalmagor.com is configured using external DNS.

% dig aitanalmagor.com
aitanalmagor.com.	300	IN	A	75.2.60.5

And

% dig www.aitanalmagor.com
www.aitanalmagor.com.	300	IN	CNAME	chimerical-bavarois-a9c7b9.netlify.app.
chimerical-bavarois-a9c7b9.netlify.app.	20 IN A	54.253.236.10
chimerical-bavarois-a9c7b9.netlify.app.	20 IN A	54.66.176.79

However it also appears the domain is configured to use Netlify DNS

% dig aitanalmagor.com NS
aitanalmagor.com.	172800	IN	NS	dns1.p01.nsone.net.
aitanalmagor.com.	172800	IN	NS	dns2.p01.nsone.net.
aitanalmagor.com.	172800	IN	NS	dns3.p01.nsone.net.
aitanalmagor.com.	172800	IN	NS	dns4.p01.nsone.net.

This is quite likely the cause. If you need/want to continue using external DNS, remove the domain from Netlify DNS. And vice versa.

Hi, @mayan.asif. The domain is not using Netlify DNS. This can be confirmed using the WHOIS data for the domain:

$ whois aitanalmagor.com | grep "Name Server:"
   Name Server: NS-1314.AWSDNS-36.ORG
   Name Server: NS-1929.AWSDNS-49.CO.UK
   Name Server: NS-458.AWSDNS-57.COM
   Name Server: NS-710.AWSDNS-24.NET
Name Server: NS-710.AWSDNS-24.NET
Name Server: NS-1929.AWSDNS-49.CO.UK
Name Server: NS-1314.AWSDNS-36.ORG
Name Server: NS-458.AWSDNS-57.COM
