I’ve performed some testing on your domain. I can see that you have the Proxy enabled for all of your records except www.gogomall.com.my.
Your server is actively refusing connections on Port 443.
I am able to connect on port 80 (HTTP), but then the site times out.
This looks to be an origin server issue - your origin webserver is not responding, or is offline, or the IP Address has changed. Please inspect the Origin Configuration for any problems.
Please let me know if you have any questions or require further assistance!
