SSL subdomain setup

My apologies for the constant disturbance but then i want to set the universal ssl for my subdomains again but this time on another site For multiple subdomains but i want to test one first.
I have set the traffic to the hostname to go through Cloudflare for the subdomain but now it is telling me that the site isnt secure when i try to load the site through https
Please what can i possibly do at the point

the first site i tried it on worked very fine until this point: &

Please a quick response would be highly appreciated. Thank You
