Did your host mention this?
"and then sue a checker like https://www.whatsmydns.net/#A/actionfiguregeek.com to confirm if the correct records are resolving"
If they are using a third-party tool like that, then they won't be getting correct results. Ezoic serves as a proxy in this case (similar to Cloudflare). We then point the domain to the IP address you provided: 126.96.36.199.
The issue is when we connect to that IP address directly, not using our proxy, then we still see that hosting error as Emily mentioned earlier.
Again, your host can simply follow this guide to reproduce the error by connecting directly to your site with that IP and without Ezoic as a proxy: https://support.ezoic.com/kb/article/how-to-edit-your-hosts-file
