Ugh, code 417 is the worst. Had the same issue last week. Turns out my proxy server was stripping the `Expect` header.
Try forcing it with `curl -H "Expect:"` or Postman. If that works, it’s definitely a header thing.
Also, check if your server’s TLS/SSL is up to date. Weirdly, that fixed it for me once.
