Problem of Use 127.0.0.1 IP Address for Proxies Exercise

[SB1lal]

Hello Cesar,

I have an interesting situation for Proxies exercise:

If I use:

proxy: {
    host: 'localhost',
    port: 65535
}

I've got this:

1.  ACTUAL:    "Hello Proxies"
1.  EXPECTED:  "{\"message\":\"Client request error: connect ECONNREFUSED 127.0.0.1:65535\",\"statusCode\":502,\"error\":\"Bad Gateway\"}"

Submission results did not match expected!

Status code returned is correct

If I use:

proxy: {
    host: '127.0.0.1',
    port: 65535
}

I've got this:

1.  ACTUAL:    "{\"message\":\"Client request error: connect ECONNREFUSED 127.0.0.1:65535\",\"statusCode\":502,\"error\":\"Bad Gateway\"}"
1.  EXPECTED:  "{\"message\":\"Client request error: connect ECONNREFUSED 127.0.0.1:65535\",\"statusCode\":502,\"error\":\"Bad Gateway\"}"

Submission results match expected

Status code 502 returned from url (http://localhost:34283/proxy), expected 200.

This problem is related to 127.0.0.1 ip but I have no idea what is the problem.
