Doesn't work when launching to https

[lastmjs]

When I launch to a normal http endpoint, the authentication works fine. When I launch the same endpoint but from https, the validation breaks. The signatures are different. I haven't looked into it too much, but I think it's how the headers are handled. There are different headers set (at least in the version of Chrome that I'm using) when performing the https post than when performing the http post.

Got it to work thanks to this and this

Could we add some documentation for that in the README? That one was hard to figure out, took me a while to finally search through the issues.

Thanks for taking a look through the issues. Happy to accept a PR adding a note around this.
