Cloudflare Issue

1. Log in to the Cloudflare dashboard ↗ and select your account and domain.
2. Go to SSL/TLS.
3. Choose an encryption mode.

Limitations

Flexible mode is only supported for HTTPS connections on port 443 (default port). Other ports using HTTPS will fall back to Full mode.

If your application contains sensitive information (personalized data, user login), use Full or Full (Strict) modes instead.

Authenticated Origin Pull does not work when your SSL/TLS encryption mode is set to Off or Flexible.
