Saquib_Shaikh you could get in touch with your host to see if they have a firewall that is blocking, or check any security tools that you may have installed for website protection and whitelist Ezoic there too. If your host has already whitelisted Ezoic's Ips or implemented one of the other fixes outlined in this article: https://support.ezoic.com/kb/article/how-to-fix-origin-errors we recommend looking into it with them in case anything has been missed out, or implemented incorrectly. If you do get your IPs whitelisted with your host, you can confirm this on your Ezoic dashboard under Settings > Connection > Troubleshooting - https://pubdash.ezoic.com/settings/connection/troubleshooting.
However just to reiterate what Imogen said on your other thread - if you're using Blogger this may well be part of the issue - Blogger sites are not compatible with cloud integration with Ezoic and it can cause issues, so we'd recommend you either use our client side integration method (Basic Ads), or else move from the Blogger to Wordpress CMS. Let us know your preferred option
