[Support Guide] Troubleshooting SSL certificate errors

Hi @DevOps-Tuck,

Thanks for reaching out!

Looks like you don’t have Netlify DNS properly configured as domaincontrol.com name servers are configured instead of the Netlify name servers mentioned here:

dig reviewcleanup.com NS +trace | tail -n 6 ;; Received 543 bytes from 2001:502:1ca1::30#53(e.gtld-servers.net) in 47 ms reviewcleanup.com.	3600	IN	NS	ns63.domaincontrol.com. reviewcleanup.com.	3600	IN	NS	ns64.domaincontrol.com. ;; Received 98 bytes from 173.201.69.42#53(ns64.domaincontrol.com) in 42 ms 

I’m also showing that you have configured the bare domain and subdomain for external DNS:

host reviewcleanup.com reviewcleanup.com has address 99.83.190.102 reviewcleanup.com has address 75.2.60.5 reviewcleanup.com mail is handled by 1 aspmx.l.google.com. reviewcleanup.com mail is handled by 5 alt1.aspmx.l.google.com. reviewcleanup.com mail is handled by 5 alt2.aspmx.l.google.com. reviewcleanup.com mail is handled by 10 alt3.aspmx.l.google.com. reviewcleanup.com mail is handled by 10 alt4.aspmx.l.google.com. 
host www.reviewcleanup.com www.reviewcleanup.com is an alias for review-cleanup.netlify.app. review-cleanup.netlify.app has address 18.213.222.111 review-cleanup.netlify.app has address 54.161.234.33 review-cleanup.netlify.app has IPv6 address 2600:1f18:2489:8200::c8 review-cleanup.netlify.app has IPv6 address 2600:1f18:2489:8202::c8 

With Netlify, you’ll want to configure either Netlify DNS or External DNS not both at the same time. Since you have the domaincontrol.com name servers, the DNS Zone is inactive. You can read how to detect and fix inactive DNS Zone here:

TLDR: if you want to use Netlify DNS, you’ll need to use the Netlify name servers mentioned above. You’ll also want to remove the A Record for reviewcleanup.com that points to 75.2.60.5 and the CNAME Record for www.reviewcleanup.com that points to review-cleanup.netlify.app.

If you want to use External DNS, you’ll want to remove the Netlify DNS Zone here:
