My website not working

I already have a cloudflare ssl ,why my wordpress website Really Simple SSL
Test results is :Really simple SSL cannot detect a valid SSL certificate.
pls help!!!

Hi @geyun.2011,

Do you have a certificate on your server and your SSL mode at Cloudflare set to Full (strict)? If not, you need to get that sorted, and that may well fix the warning you get.

I have Flexible SSL

Thai is most likely the issue, not only is Flexible insecure, but it often breaks stuff like this.

You should just get an SSL certificate on your server and switch that to Full (strict).

I set to “full”,still not working

What error do you get and what is not working?

What’s the domain?

This site can’t provide a secure connection
