So there are 2 things I noticed when looking at your site settings.
1) Caching is not turned on. Without any caching, your site will not update correctly and may not show ads if the visitors are not looking at the right version of your page. Since you are name server integrated, you have access to our CDN, and you can enable caching by going to your Ezoic dashboard > Leap > Caching > click on Enable CDN.
2) Objectionable content. When your site has been flagged for violations, Google may reduce the number of ads shown on your site or not show any at all. It looks like some of your pages have been flagged which you may want to look at and fix. To find these, go to your Ezoic dashboard > Ezoic Ads > Ad Restrictions > Objectionable Content.
