How to Fix SSL Certificate Error in AI-Built Apps

HTTPS connections fail due to expired, self-signed, or misconfigured SSL certificates. AI-generated deployment configs often skip TLS setup or use insecure workarounds.

Error messages you might see

Error: unable to verify the first certificate
SSL routines:ssl3_get_server_certificate:certificate verify failed

Why this happens in AI-generated code

1

Self-signed certificate in production

AI uses development certificates that browsers and clients don't trust.

2

Missing intermediate certificates

The server sends only the leaf certificate without the full certificate chain.

3

NODE_TLS_REJECT_UNAUTHORIZED disabled

AI code sets this env variable to '0' as a quick fix, disabling all certificate validation.

How to fix it

1

Use Let's Encrypt for free certificates

Set up certbot or use a platform like Vercel/Cloudflare that provides automatic SSL certificate management.

2

Include the full certificate chain

Concatenate the leaf certificate, intermediate certificates, and root CA in your certificate file.

Frequently asked questions

Is it safe to set NODE_TLS_REJECT_UNAUTHORIZED=0?

Never in production. It disables all certificate validation, making your app vulnerable to man-in-the-middle attacks.

How do I test my SSL configuration?

Use SSL Labs Server Test (ssllabs.com/ssltest) to check your certificate chain and configuration.
