HTTPS / TLS
Encrypted transport
A certificate helps browsers validate encrypted connections to a domain.
Services
HTTPS works best when the domain and DNS story is already coherent.
Vercel can provision certificates automatically for correctly configured domains. This page explains the process; it does not change DNS, issue a certificate, or claim that a current certificate is active.
Vercel
Automatic provisioning
Correctly connected domains can receive managed certificates through Vercel’s platform.
Coverage
Apex and www
Plan whether both the apex domain and www hostname should resolve and redirect consistently.
Validation
DNS must agree
Certificate validation depends on correct DNS records and adequate propagation time.
Renewal
Managed lifecycle
Automatic renewal behavior depends on the platform and a continuing valid domain configuration.
Troubleshooting
Mixed content
A secure certificate does not fix insecure images, scripts, or other browser-blocked mixed content.
Custom certificates
Use when needed
Some enterprise or legacy needs require a separate reviewed certificate approach and should be scoped first.
Before you ask for help
Bring the hostname, DNS owner, and exact browser error.
That makes a support intake safer and more useful without sending a public page access to a provider account.
