I don't get what's wrong. Wrong version maybe ?

Hi @snapapplabs, could you provide the sample code that you execute?

We can try to reproduce issue and help you to find the current problem.

Hi @Taluu This error is thrown when using cluster module in nodejs

Fatal error: Uncaught UnexpectedValueException: The server returned an unexpected value. Expected "HTTP/1.1 101", had "HTTP/1.1 400"

From what I can see in both errors, you are hitting a 400 (bad request). So that means that either the version is wrong (2.x instead of 1.x, or something like that).

You will need to check what request is made, and try it yourself.
