Host suggested Cloudflare SSL issue, possible certificate related.
If that’s a subdomain, you’ll have to make sure you’ve a valid certificate installed at your host and configure it correctly at the Cloudflare setting it to Full Strict.
If that’s not a subdomain, unproxy it. For more info, read the doc:
Error occurs for the mail subdomain, and also for the domain.
Also, checked setting is Full or Full Strict, and created Cloudflare certificate. Still receive error.
Your origin is receiving the Perot. I’d recommend contacting your hosting provider.
Thanks all, will try the hosting provider again.
