What is the issue you’re encountering

SSL for Subdomain Not Working, Main Domain OK

What steps have you taken to resolve the issue?

Proxied and unproxied DNS records
Disable Universal SSL for a couple of hours. Maybe re-generating would help but I wasn’t able to find how to re-generate it.
Full (strict)

What are the steps to reproduce the issue?

Hello! I would really appreciate the help of the community! And I will definitely post the working solution here if I find one.

About a month ago, I started using Cloudflare with SSL for my website, ecogeartailgating.com. However, after adding a subdomain, rental.ecogeartailgating.com, I noticed that SSL is not working on the subdomain. I’ve spent the past 10 days trying to troubleshoot the issue myself, but haven’t been able to find a solution.

This is what I see:

Furthermore, now since having SSL certificate on the Hostinger panel for both main domain and sub-domain, you can enable proxy .

However, domain currently isn’t using Cloudflare nameservers anymore:

Name Server: ns1.dns-parking.com
Name Server: ns2.dns-parking.com

What was selected for your SSL settings under the SSL/TLS tab?

Thank you for your reply! After creating the topic, I had the idea to change the nameservers back to my hosting provider, ensure that both SSL certificates (for the main site and subdomain) were working correctly on my hosting side, and then change them back to Cloudflare.

Now I know that everything is perfect on my hosting side, just as it was on your screenshot. However, the issue reappeared after I pointed the nameservers back to Cloudflare. Currently, the nameservers are pointing to Cloudflare, the main domain is working, but the subdomain still has the same issue as described in my first post.

Perhaps I should delete and regenerate the SSL certificate on Cloudflare, as I generated it before creating the subdomain. Is this possible on a Free plan? Or something else?

"It is set to Full (Strict), but my subdomain isn’t appearing in the Edge Certificates tab.

subdomain

Is the sub.domain.com covered with the valid SSL certificate at the origin host, or maybe not?

[marketing203]

Yes. SSL settings for the subdomain are attached. They’re identical to the main domain’s settings.

If there’s a way to regenerate the Cloudflare SSL certificate, I’d like to try it. I created the certificate before adding the subdomain, and even though I’ve updated the DNS settings, Cloudflare’s SSL certificate still doesn’t include the subdomain.

Maybe if something else can be done? My subdomain meets all the requirements, but despite this, CloudFire doesn’t work.

It is a pity to stop using CloudFire. Apparently, it doesn’t work for free; I just wasted my time. Perhaps when we become a big company and have a budget, I will create a paid account, contact paid support, and they will help me.
