Where you seeing an Origin error? If so then these are typically caused by either a mismatch in DNS records or the SSL setup between your original setup and the Ezoic setup, or by the host or a security layer blocking requests going via Ezoic servers.
Here is a guide on how to resolve these errors: https://support.ezoic.com/kb/article/how-to-fix-origin-errors
Here are some checks you can make:
1-Check that the DNS records at your host match those you have entered at Ezoic.
A way you can check the IP we have in Ezoic is correct is to check at your host. Or you can also check this is by editing your host file to connect to the IP you have in your Ezoic dashboard.
If you can edit the host file and connect to the origin server IP without an error then the IP we have for your site at Ezoic is likely correct.
This would then mean the error is likely coming for your host blocking requests. in which case you should implement the solutions found in the guide i shared above.
2- Check your Ezoic SSL is setup correctly: https://support.ezoic.com/kb/article/using-ssl-with-ezoic
3- It may also come from security plugins you are using. If you disable them and the error is removed then the plugin will have been blocking requests. You can either keep this off or whitelist Ezoic Ips in the plugin. Again you can see how to do that here: https://support.ezoic.com/kb/article/how-to-fix-origin-errors
