TLS expiration
This handler can retrieve TLS certificates for a website and fail if its expiration date falls within a configurable window of time. This can help detect issues in your renewal processes and be used as a last resort reminder if you still do it manually.
For now, only TLS certificates served on port 443 are supported.
