Can the server serve HTTP/1 too? If not, does anyone know of a server that can serve both HTTP/1 and HTTP/2?

  Yep. A client must declare that it supports HTTP/2, otherwise the server will fall back to HTTP/1.1. Also, any plaintext HTTP connection will not be HTTP/2 (major implementations of HTTP/2 don't support plaintext).

    Thank you, I never realised that was how it worked!
