Read the doc carefully, socks5_auth_config_path is not supported by the basic configuration format.

Read the doc carefully, socks5_auth_config_path is not supported by the basic configuration format. Of course, I wrote it according to the document.

I believe you are running an old version that doesn't support socks5 auth.

shadowsocks-v1.17.1.x86_64-unknown-linux-musl.tar.xz

It seems that the method macOS was using is not PASSWORD.

Rerun sslocal with -vvv and see what exactly the Auth request was.

Well, the request from client didn't require any authentication. So the request was rejected.

The error message is misleading, I will fix that later.

ok, maybe the mac's client has problem. I will try other clients.

same problem on Mac Os. https://github.com/rofl0r/microsocks/issues/17

@hellomsg I can confirm the issue is related to MacOS's client...
