Can't connect via ipv6 proxy

[polRk]

I have the proxy:

IPv6 :

1. connection IP - 1.1.1.1 (example)
2. username - hiden
3. password - hiden
4. IPv6 - ::1

const client = new TelegramClient(new StringSession(session), apiId, apiHash, {
  useWSS: false,
  useIPV6: true,
  connectionRetries: 3,
  proxy: {
    ip: "1.1.1.1", 
    port: 1111, 
    username: hidden, 
    password: hidden, 
    socksType: 5
  },
})

await client.connect()

Socks5 proxy rejected connection - ConnectionRefused
