Chef omnibus installer gets HTTP 405 when attempting to download Chef 12 Windows installer


We are experiencing an issue whereby the Chef omnibus installer encounters an HTTP 405 error when it attempts to download the Chef 12 Windows installer from; here’s some relevant output from a Test Kitchen converge step running against the latest Windows 2016 Server AMI in AWS:

-----> Installing Chef Omnibus (12)

Weirdly, this very same Kitchen configuration was working fine yesterday, so I’m at a loss for what changed.


Could you provide a sanitized version of the .kitchen.yml?


Doh. I forgot to come back and update this. Turns out a couple of our AWS IPs were blacklisted (and since removed); I’m puzzled as to why, because we don’t bootstrap very many nodes on any given day (measured in 10s, certainly sub-100 even if some sort of weird edge case were to occur). Are there particular rules about downloads per $time_period, or something else we might’ve encountered?


Our CDN does some rate limiting so if you’re hitting that you can reach out to and they can potentially whitelist IP ranges with upstream.


@cheeseplus Thanks! We’re also going over things on our end to ensure we’re not accidentally misbehaving (I’d rather misbehave on purpose… :wink: ).
