I have a very strange issue and I hope to find anyone who can help with it!!
I created a subdomain
and all the subdomains working very well
The issue in KSA Country some clients there, some ISP lines show this error from the browser when accessing the subdomain
despite this works in all countries very very well
So Is there any option by default to block or some distractions in the SSL? I meant by default because I didn’t do anything in the default configuration in the Cloudflare account
