I don't see e.g. a GitHub repo to comment on, but the HSTS header example is `Strict-Transport-Security: max-age=63072000; includeSubdomains; always`
`always` has no meaning, and probably indicates a typo in an nginx configuration.
As others have pointed out, there is other TLS advice here that you shouldn't follow blindly, like a 4096-bit cert (especially if your intermediate is smaller) or TLS 1.2 only. Rationales and trade-off explanations would help avoid misuse of this checklist.
The SSL Labs checker is probably the best tool to use for all the automatable TLS checks.
