You probably ended up on this page, if you are using one of my plugins and received an error that the machine cannot contact a website.
This error occurs if you have not setup DNS correctly. On linux based systems, check the file /etc/resolv.conf
A valid configuration is:
# Nameserver must be a public accessible DNS server which resolves
These nameservers are from google
On windows servers, go to your control pannel -> Network and Sharing -> Change adapter settings -> Select the correct adapter -> Properties
Then apply the correct settings as shown below
