Are TCP servers dead?

[4310V343k]

I'm unable to connect to them via netcat, telnet or python's socket module

$ nc 212.17.118.125 2727
*empty output*

$ telnet 212.17.118.125 2727
Connecting To 212.17.118.125...Could not open connection to the host, on port 2727: Connect failed

    s.connect(("212.17.118.125", 2727))
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I'm unable to solve 27 hackit because of it since it uses server's FS to store correct passwords

fs.writeFile("../data/tmp/"+pw, "OK", function(err) {
          fs.chmodSync("../data/tmp/"+pw, 0777);
            if(err) {
                return console.log(err);
            }
        });

Sure looks like it. Also the image link I've been given for 31 doesn't exist: https://www.0xf.at/data/imgs/d92b0d88d8eaad46dc9ec19012302692.jpg
