[Bug]: Vless Over QUIC

[radiumatic]

I have a sing-box vless-over-QUIC server and shoes fails to work with it. I don't think connectivity is the problem as trying to open connections to nonexistent domains instantly results in an error, not to mention that the same configuration works with sing-box and the older version of Xray-core that had QUIC support.

- address: 127.0.0.1:8888
  transport: tcp
  protocol:
    type: socks5
  rules:
    # Directly connect to 192.168.*
    - mask: 192.168.0.0/16
      action: allow
      client_proxy: direct
    # Forward all other connection requests through a Vmess WSS server.
    - mask: 0.0.0.0/0
      action: allow
      client_proxy:
        - address: "example.com:443"  # Replace with the actual server address and port
          protocol:
            type: vless
            user_id: "A UUID"  # Replace with your actual UUID
          transport: quic
          quic_settings:
            verify: true  # Whether to verify the server's certificate
            sni_hostname: "example.com"  # Optional SNI hostname; can be left unspecified
            alpn_protocols:
              - "h3"  # Specify the ALPN protocol; e.g., HTTP/3% 

The error:

[2024-10-15T15:13:41Z ERROR shoes::tcp_server] 127.0.0.1:49834 finished with error: Custom { kind: UnexpectedEof, error: "failed to setup client stream to www.google.com:443: early eof" }

can you share any logs from the server side? since it's an early eof, i assume that the server detected some issue and decided to disconnect the client.

also, when this was written, i was not aware of any server the shoes QUIC VLESS client could be tested against. the shoes QUIC VLESS server did work correctly when tested against iOS Shadowrocket.

Here is the log from sing-box running as a server on my local machine:

INFO[0054] [2526169208 0ms] inbound/vless[vless]: inbound connection from 127.0.0.1:32783

That's it. Not sure what it means. A quick search says at some point it also occurred with cloudflared (cloudflare's port forwarding program written in go).

Has anyone found a solution or at least a clue to the reason of this?
