Ok so here’s my problem.
I know using SSL is highly recommended especially on an ecommerce website. This is why I want to use Full (Strict). And it seems to work, but only for domain.com not www.domain.com not mobile.domain.com only domain.com. From web docs it says the issue is more than likely a self signed certificate. But this is even for Cloudflare origin certs. And yes I believe it was configured properly assigned to *.domain.com and domain.com. I gotta be missing something here. The cert works in strict mode, but only for domain.com Error received was 526.
