The server refused the handshake

Something in your onboarding process broke the TLS configuration, and every second of delay costs trust, uptime, and customers.

A secure onboarding flow depends on a clean, predictable TLS setup. Miss one step and your HTTPS connections fail under load. The onboarding process for TLS configuration must be tightened from the first command to the last certificate. That means defining certificate authorities, ensuring key pairs are correctly generated, and locking protocol versions to known-good standards. No wildcards, no outdated ciphers, no guessing.

Start with a pre-flight checklist.

1. Generate private keys with strong algorithms.
2. Create CSRs that match exact domain names.
3. Validate certificates against your CA.
4. Configure TLS protocols to reject deprecated versions like TLS 1.0 and 1.1.
5. Test handshake integrity in a staging environment before pushing live.

Automating these steps in the onboarding process reduces risk. Use configuration scripts that define TLS parameters in code, version control them, and link them to deployment pipelines. Every onboarding run should be repeatable and auditable. Logging every handshake result exposes issues before they hit production.

Strong TLS configuration in onboarding prevents man-in-the-middle attacks, protects customer data, and makes compliance audits straightforward. It also speeds up the path from first commit to live traffic. When developers join a project, the onboarding flow should provision certificates, inject configuration files, and validate endpoints automatically.

Failing at TLS in onboarding is not a minor bug—it is a security breach waiting to happen. Treat configuration as code. Test it, monitor it, and lock it down.
