Current Behavior

sing-box server:

    {
      "type": "hysteria2",
      "listen": "::",
      "listen_port": 443,
      "users": [{
        "password": "bar"
      }],
      "tls": {
        "enabled": true,
        "server_name": "a.b.xyz",
        "acme": {
          "domain": "a.b.xyz",
          "email": "i@examle.com"
        }
      }
    }

dae config:

a: 'hy2://bar@a.b.xyz:443'

dae log:

level=warning msg="handleConn: failed to dial xxxx:80: connect error: CRYPTO_ERROR 0x178 (remote): tls: no application protocol"

If use the original server-side program of hy2, there will be no problem.

尝试使用hy2原版的客户端程序连接试试 如果也连接不上 就是sing-box问题

[douglarek]

a workaround of sing-box on the server side is to add an extra alpn:

      "tls": {
        "enabled": true,
        "server_name": "example.com",
        "alpn": "h3",
        "acme": {
          "domain": "example.com",
          "email": "i@example.com"
        }
      }

If using clash meta as the hy2 client, and sing-box as the server, this method should also be feasible.
