Simply doesn't work

[QuantumDisposition]

Listening port drops connections. Literally nothing is happening. Debug log shows nothing. An nginx worker exists with signal 8.

2022/12/23 22:40:35 [alert] 57408#101792: worker process 57526 exited on signal 8

log_format socks5 'socks: $socks_connect_addr $socks_name $socks_passwd';

    socks;
    socks_proxy_bind [external IPv4];
    socks_user_passwd test1 test2;
    access_log ngx_socks_access.log socks5;
}

testing with:

# curl -v --socks5 test1:test2@10.10.0.1:8080 ifconfig.me
*   Trying 10.10.0.1:8080...
* connection to proxy closed
* Closing connection 0
curl: (97) connection to proxy closed

nginx version: nginx/1.23.3

Compiles fine. Stream is enabled (and works).

[QuantumDisposition]

Works if curl provides user/password AND the server block is defined WITHOUT socks_user_passwd.

curl -v --socks5 test1:test2@10.10.0.1:8080 ifconfig.me

However, seems that 1 try is around 5-6 is still being dropped anyway (for seemingly no reason).

[QuantumDisposition]

Apart from the user/password bug and sudden drops sometimes, good job. This is an incredibly helpful functionality.
