Adzilla Problem

I signed up for Adzilla and set up the account, which was straightforward. However, after retrieving the domain, Iā€™ve been receiving the message below from the Adzilla program for the past week. As a result, I havenā€™t been able to make any progress with Adzilla. The message it is giving me is Web Servier returning an unknown error. It is indicating that Cloudflare and brower are working however the domain indicates Host error. It has been approximately 5 days. if anyone is familiar please let me know.

Hey! Just started few weeks ago, Iā€™ve been there and got help from support! Donā€™t sign up for adzilla! It comes free with program for a year! It will pop up at the top of the screen every time just ā€œXā€ it out. Do not sign up for anything unless you email your support team, and they say too!

Hope this helped!!
