FAQPage Schema
How do I configure a custom domain for my Render web service?▼

To configure a custom domain, add it to your Render service and create the required CNAME, ALIAS, or A records at your provider. Render validates these DNS entries to enable TLS and route traffic to your application.

What DNS records do I need for apex domains on Render?▼

Apex domains on Render require ALIAS or A records pointing to Render, while subdomains use CNAME records. You must configure these specific DNS entries at your provider to pass domain verification.

Why is my TLS certificate not issuing on Render?▼

TLS certificate issuance fails when DNS records are incorrect or missing required CAA records. Validate your CNAME, ALIAS, or A records and ensure CAA entries permit certificate authorities to issue the certificate.

Does Render support wildcard domains and Cloudflare DNS?▼

Render supports wildcard domains and integrates with Cloudflare, Namecheap, and other DNS providers. You can configure wildcard DNS records and manage TLS validation across these specific providers.

Can I disable the default onrender.com subdomain after adding a custom domain?▼

Yes, you can disable the default onrender.com subdomain after setting up your custom domain. Configuring and verifying your custom domain with proper TLS enables you to turn off the default subdomain routing.
