Unsupported socks version 47.

[Bayroom]

I am using openwrt-shadowsocks-rust on openwrt_22.03-rc4.
Installation went well but when I launch "sslocal" with a configuration file I created I get error telling:

ERROR socks5 tcp client handler error: unsupported socks version
ERROR unsupported socks version 47

PS: In my configuration file I specify multiple ports using "Extended multiple local configuration". But when I use up to 7 ports, I don't get this error, starting from 8 ports I get error.

Any Ideas about this issue or what causes it ?
