nomadbytrade I'm sorry to hear that you're experiencing an Origin Error preventing you from logging into your site.
As we're not seeing this on every page, I recommend following the troubleshooting steps outlined in this support article on how to fix Origin Errors: How to Fix Origin Errors.
If you've already followed the steps in the guide and the Origin Error persists, I recommend checking your DNS records in Ezoic match those from Siteground perfectly, you can check and edit these in settings - DNS. And that your SSL is configured correctly: https://support.ezoic.com/kb/article/using-ssl-with-ezoic
If you followed these steps, the next thing I recommend checking is if there's any plugins on your site that may be preventing you from logging in or accessing the page, or any other firewalls / security plugins where you will need to whitelist the IPs in the origin errors article.
