"A" record does not work ! (521 status code)

Hey , I made an A record named “test” for test.neodiom.com to one of my server’s IP ( value : ) and record set successfully in my Cloudflare DNS management.
I installed openlitespeed web server and as you can see it is working as well =>
but the problem is after almost one day test.neodiom.com does not send the IP response and I have 521 error (test.neodiom.com) !
Does anyone know what is the problem ?
Thank you

UPDATE: For people who is using openlitespeed , solution is here : A Guide to Setting up SSL on OpenLiteSpeed • OpenLiteSpeed

521s are covered at Community Tip - Fixing Error 521: Web server is down.

In your case the issue is that your server is not configured for HTTPS. You need to complete that setup on your server first.
