Fly Proxy H/2 Details

It’s definitely not passthrough if you have the http handler. If you want to pass through http/2, you can enable only the tls handler and use the following port definition: [[services.ports]] handlers = ["tls"] port = "443" tls_options = { alpn = ["h2", "http/1.1"] } Or just h2 in the list of alpn. Then your app will need to understand http/2 over plaintext.
