Ssl not working

Here’s my site : mp3chest.com … when i try to open https version it gives me error , can you please check . I get error “connection not secure”

It’s coming up correctly for me. Are you sure you’re hitting the Cloudflare version? Maybe DNS needs some more time to propagate.

it’s already been two days that i have enabled flexible ssl … and also it is working on my side but not in many places of the world i tried to use the tools like Website Uptime Test: Check Website Status | Uptrends and it shows that site is not working in many place … attached a screenshot also . Also tried this site https://asm.ca.com/en/ping.php and it is also shows that site is not working in many place

please help.
