What problem does it solve? Setting up custom domains on Render involves DNS record configuration, certificate issuance, and provider-specific quirks that often cause verification failures or silent TLS errors. This Skill guides you through the entire process so your domain resolves correctly over HTTPS. ## Core Features & Use Cases - DNS Setup Guidance: Provides exact CNAME, A, and ALIAS record configurations for subdomains and apex domains across providers like Cloudflare and Namecheap. - TLS & Certificate Troubleshooting: Diagnoses certificate issuance failures caused by CAA records, stale AAAA records, or premature verification attempts. - Wildcard & Blueprint Support: Covers wildcard domain setup with the three required CNAME records and declarative domain configuration in render.yaml blueprints. - Use Case: You deployed a web service on Render and want app.example.com to serve it over HTTPS. This Skill walks you through adding the domain in the Dashboard, creating the CNAME record, verifying it, and disabling the default onrender.com subdomain. ## Quick Start Ask the assistant to add the custom domain app.example.com to your Render web service and configure the DNS records with Cloudflare.
