This is because another process is laready listen on this address:port.

To listen on temporarily non configured addresses you may use something
like this:

server {
listen 80;
}

server {
listen 213.167.72.152:80 default;
...
}

server {
listen 213.167.72.1:80 default;
...
}

nginx binds to *:80 only, but tests an address where a request comes to.
