D-Link DSP-W110-C70C unable to configure

I have to configure my D-Link WSP-110 plug.
I get the following response from my log file:

17-02-02 21:07:09 WARNING (Thread-7) [pyW215.pyW215] Unable to open a connection to dlink switch http://192.168.1.xxx

The router is giving me the above IP address 192.168.1.xxx and I have used my Email address, admin and my user name Mike37922 for the user name.

I have changed the password from my APP password to the devise PIN number with no effect.

This device works well with the D-Link APP.

Can someone help.
