Issue with the https certificate

My https certificate stopped working and I cannot figure out why.
My netlify site is and I’m trying to access it via

The domain is hosted on godaddy, and I’ve applied the suggested CNAME dns entry

In the netlify control panel I don’t see any error.

Yet, when I try to access I get an invalid certificate error.

What am I doing wrong?

HI @pierobond,

Thanks for reaching out and welcome to Netlify’s Support forums!

I see you have configured Netlify DNS for the domain here:

However, you are using name servers instead of the Netlify name servers.

host -t ns name server name server

I also show that you have External DNS setup for the domain:

A Record for pointing to

host has address mail is handled by 10 mail is handled by 20 mail is handled by 20 mail is handled by 30 mail is handled by 30

CNAME Record for pointing to

host is an alias for has address has address has IPv6 address 2600:1f18:2489:8200::c8 has IPv6 address 2600:1f18:2489:8202::c8

You’ll want to either use Netlify DNS or External DNS and not both.

We have a Support Guide here on how to detect a inactive DNS Zone:

The solution is either to delete the DNS Zone as outlined here. Or to use Netlify’s name servers mentioned here. If you decide to use Netlify’s name servers, you’ll need to remove the External DNS configuration of the A Record pointing to and the CNAME Record pointing to

Having both External DNS and Netlify DNS configured can cause issues with the SSL Certificate getting generated or renewed.

Let us know if you have any questions.

Thanks. I’ve deleted the DNS zone in netlify a couple hours ago, but I still get the same error.
How long should it take?

Up to 48 hours. If you are still experiencing this issue in 2 days please reach back out.

Hi @pierobond,

Thanks for the follow-up. You should be all set with the SSL Certificate.
