API not work for me

[thalissondev-xx]

API does not work for me, I try to make connection but is carrying up to timeout error, debugging api, I realized that the fetchData method of the Connection class, this code

while (strlen ($ data) <$ length) {
$ Data = socket_read ($ this-> connection, $ length).;
}

socket_read returns empty, then the infinite loop.

I'm trying to make the connection in ec2 my localhost;
