I received an email from a customer saying that their internet security (kaspersky) blocked them from going to my website checkout. I have an SSL certificate with my hosts but they’re saying that as my domain points to Cloudflare, it’s not valid. I have the following selection enabled in cloudflare:
Encrypts end-to-end, using a self signed certificate on the serve”
Is this enough? Or is there anything else that could be causing the block?
