# W5500 server is 255.255.255.255 error

## Question

Asked by Indramal on 2019-09-10 in Ethernet Chips.

I am using W5500 module (not shield) with Arduino. I installed Ethernet2 library and I put example of WebServer to the Arduino.

Then serial output give “server is 255.255.255.255”

What is this problem?

I think the connection between the Arduino and the W5500 module is wrong. Check other register values using the code below.
Serial.println (Ethernet.subnetMask ());
Serial.println (Ethernet.gatewayIP ());

Now the connection is ok. But Server not showing in computer. I directly connect through Ethernet cable.

When I go to page it is show

> ERR_CONNECTION_REFUSED

Is it a cable problem? Cross or nor?

Serial Output give

> server ip 192.168.1.177

My home network is also 192.168.1.__ range.
