BUG: NekoBoxForAndroid is not working with VLESS+OpenVPN+UDP [proxy mode only]

[Cancer-zern]

Describe the problem

I have Windows application Nekoray and configuration for [VLESS-Reality] OpenVPN working via socks5 proxy by 1194/udp not any issues. The same configuration Xray+OpenVPN on Windows is working fine

When I'm configuring on NekoBoxForAndroid proxy mode only OpenVPN is not working with UDP and the openvpn application is not connecting NekoBoxForAndroid+[VLESS-Reality]+[OpenVPN 1194/udp] is no working NekoBoxForAndroid+[Shadowsocks-2022]+[OpenVPN 1194/udp] is working fine

[VLESS-Reality] configuration { "_v": 0, "addr": "$ip-address", "flow": "xtls-rprx-vision", "name": "ProfileName1", "pass": "$uuid", "port": 443, "stream": { "alpn": "h2", "ed_len": 0, "insecure": false, "mux_s": 0, "net": "tcp", "pac_enc": "xudp", "pbk": "$PubKey", "sec": "tls", "sid": "$ShortId", "sni": "www.microsoft.com", "utls": "chrome" } }

[Shadowsocks-2022] { "_v": 0, "addr": "", "method": "2022-blake3-chacha20-poly1305", "name": "ProfileName2", "pass": "$Key", "port": 23 }

[VLESS] connection working with OpenVPN+udp configuration working on:

1. Windows [Nekoray app cores: xray/sign-box]
2. Linux [Xray-core/sign-box]
3. Openwrt [Xray-core/sign-box]
4. Windows [Xray-core]

How to reproduce

1. NekoBoxForAndroid v1.2.9 Configure VLESS, App settings [VPN mode to Proxy Mode only]
2. Add proxy for OpenVPN application as socks5 127.0.0.1:2080
