Subdomain error DNS_PROBE_FINISHED_NXDOMAIN

[user20465]

Hi, I have this problem (DNS_PROBE_FINISHED_NXDOMAIN) since I have activated Cloudflare on my subdomain nyumbayapaka.pakasafaris.com
I have already add an A record pointing to the server but no changes…
All my other website are working properly with same configuraton.
Please help me.
Thanks

The issue is not nyumbayapaka.pakasafaris.com but rather that you are redirecting to www.nyumbayapaka.pakasafaris.com.

That record neither exists nor would work even if you added it, as you’d also need an ACM certificate.

This tutorial covers a possible reason for the SSL_ERROR_NO_CYPHER_OVERLAP and ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors (Firefox and Chrome respectively) when seen on a subdomain.

Thanks Sandro, sorry I’m not an expert…
If I remove the CNAME www on pakasafaris.com I’m going to loose the www on the main domain in order to have the subdomain working again.
I have just migrate all my website from Siteground to Hostinger and before everithing was working properly domain and sub-domain both with www.
Why?
Thanks so much for your support.

If you require the www in front, then you will have to create the necessary record and purchase the ACM certificate. Alternatively you can keep the record unproxied.
