Hello, everyone. I have this C++ server app I'm hosting on my computer (source code on GitHub<https://github.com/DragonOsman/currency_converter> -- I'm using Google Maps as a GUI, and it's basically a currency converter app). I was recently having SSL issues on it, but after sorting them out I have another issue: this error came up: Lines 625 and 626: handshake: unsupported protocol (SSL routines, tls_early_post_process_client_hello) This is likely a HTTP/2 upgrade request inside a TLS ClientHello message, no? And if it is, how do I parse the ClientHello message to extract it and respond?
Boost.Beast, the low-level HTTP/S and WebSocket on top of Boost.ASIO that I'm using to handle HTTPS, doesn't support this and it also doesn't directly support HTTP/2. For HTTP/2 I could just relegate to a server does support it, though I'll need one that supports POST requests unless there's a way for me to use my own server code through a HTTP/2 proxy server (hopefully this is possible). Anyway, would someone please help me figure out how to parse the ClientHello for the request in question? Thanks.
