Why is my SSL certificate not auto-renewing on my hosting account?

Automated SSL certificate failures occur when domain validation scripts get blocked by custom firewall filters, or when your root domain’s external server routing is misconfigured.

“This is usually a firewall quietly blocking the validation script, or a routing setting that’s slightly off. I’ll get your certificate renewing automatically again within 24 hours for $99.”
