"connected": false after subscribe to startum

[cisco0x60]

I'm simply doing a telnet to the excavator process to test it. It runs at localhost:6666

This is the result code I got from shell:

[user@pc ~]$ telnet localhost 6666
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
{"id":1,"method":"subscribe","params":["nhmp-ssl.usa.nicehash.com:443", "xxxxxxxxxxx--MyNiceHashWallet--xxxxxxxxxx.nuxhash:x"]}
{"id":1,"error":null}
{"id":1,"method":"subscribe.info","params":[]}
{"id":1,"address":"nhmp-ssl.usa.nicehash.com:443","login":"xxxxxxxxxxx--MyNiceHashWallet--xxxxxxxxxx.nuxhash:x","connected":false,"server_status":"Success","error":null}

Even if I got no errors from subscribe, I got "connected":false
