Thanks for reaching out. Your site is up on our end at the moment which means that we can rule out a DNS or SSL mismatch as the cause of the issue since if that were the case the site would be down consistently rather than intermittently.
This means the errors are being caused by an issue on the origin server, the host, or a security layer blocking requests. Depending on where requests are being blocked, you can resolve this either by whitelisting Ezoic's IPs in security plugins or by asking your host to implement one of these fixes on their end:
Here's the list of IP addresses to whitelist, if you choose this solution, please let us know once this has been completed:
We are here should you need anything else.
