outgoingConnectionHttps working differently than curl or superPool

So I was doing some http(s) requests with the akka http client and noticed that some pages worked differently than curl, for instance curl “https://github.com/akka/akka-http.git/info/refs?service=git-upload-pack gives basically the same output as git ls-remote (in fact it’s what git ls-remote uses) however when using akka http connection level api. Any ideas as to what might be going wrong? I’m using akka-http 10.1.3 and akka 2.5.14.

Here’s some code that demonstrates my issue https://pastebin.com/XNA5d9uF but basically I get 404’s from github which indicates that something different is happening. I’ve tried adjusting the headers to match and still nothing.
-Thanks

So it turns out outgoingConnectionHttps is working differently than superPool, I guess I’m missing something subtly wrong when using outgoingConnectionHttps
