Google DNS
I can't access LiveHelpNow website, i can access other websites without any issues.
Please follow the link below to configure your computer to use Google DNS:
https://developers.google.com/speed/public-dns/
This does not guarantee to fix your issue, yet it will still speed up your internet browsing experience.
After Google DNS has been configured on your computer please clear all your browsers' cache and restart your computer.
Should the issue persist, please contact LiveHelpNow support.
