SSL cert doesn't exist for subdomains. Root site works correctly

(edited)

I am having an SSL cert issue when accessing subdomains of kmpfr.co. www.kmpfr.co works, but I get cert issues when accessing subdomains such as demo.kmpfr.co. SHOT 21.20.11@2x

Please let me know exactly what I have to do to solve the SSL issue.

NOTE: I have a 'rewrites' in Vercel.json, but your AI seems to think it isn't the issue:

  "rewrites": [
    {
      "source": "/widget",
      "destination": "/api/widget"
    }
  ],

Domains (this did not show invalid configuration previously... not sure what changed)

SHOT 21.17.15@2x

When I click the "Enable Vercel DNS" button, I see SHOT 21.21.57@2x

Thanks!

Hi,

I don't see demo.kmpfr.co is added to any project. Can you add it and let me know if you are still facing issue?

Note that adding *.example.com on project doesn't mean it will be accessible using any-subdomain.example.com. You need to expilictly add the domain in the project, or specific deployment using alias.

I have a multi-tenancy app, so I need to SSL support for ANY subdomain.

I've changed some DNS/NS records on my registrar and will await propogation and reply back with the results.

I changed my DNS/NS settings in my registrar (Porkbun) and it seems to be working now. FYI to others:

I removed all CNAME and A address records in my DNS settings. Here is my current config: dns

I then replaced my Nameservers with the following:

ns1.vercel-dns.com ns2.vercel-dns.com

I then double checked that I had added the domains kmpfr.co and *.kmpfr.co in my Vercel Domains page.

After waiting a day for propogation, this seemed to solve the issue.
