Hi charmbeautify - hope you're having a nice week!
What exactly was shared with the Host?
And were they able to implement any of the fixes - or did they just say 'we're not seeing it' and leave it there?
The reason we ask is because, as stated prior, origin errors aren't going to show on every visit necessarily. It's related to security settings identifying certain IPs and blocking them from accessing the site. Ezoic uses quite a large range of IPs from AWS, so it's possible that the error would come-and-go so to speak if there hasn't been a fix put in place.
Our suspicion is that during the last review, some of the IPs (as I was able to recreate) were being blocked from accessing the site properly, which would lead Google to denying the domain.
We can't say for certain that's the case - as Google provided 'low value content' as the reasoning, but we want to make sure we can eliminate the errors as a potential cause of the denial.
If the Host is willing to put any of those fixes in place, we'd say go ahead and re-apply via AdManager MCM again.
