Thanks for opening this issue!

It's supported, I just tested it on my laptop and it works. If you encounter problems, please provide the configuration file.

You're right, it was my issue. Enabling UDP requires adding packetEncoding=xudp to the node connection settings.

Please tell me the software version and configuration of the server.

In addition, I'm not sure, but you could try changing the group policy to fixed.

I mean I need the server software to test it. I tried to use V2Ray v5.16.1 and Xray v1.18.3, it's work.

服务器配置(Xray 1.8.0)：

[[inbounds]]
tag = "vless-ws"
listen = "/dev/shm/websocket.socket,0666"
protocol = "vless"
[inbounds.settings]
decryption = "none"
[[inbounds.settings.clients]]
id = "mitsuha"
[inbounds.streamSettings]
network = "ws"
security = "none"
[inbounds.streamSettings.wsSettings]
path = "/websocket"
[inbounds.sniffing]
enabled = true
routeOnly = true
destOverride = ["http", "tls", "quic"]
