Cloudflare issue with sentora

[testing]

I am trying to use cloudflare but when i change my name server to cloudflare my site become inaccessible. I changed my ns both from domain registrar and dns manager from sentora panel. It didn't work. I also just changed ns from sentora alone but that didn't work also.
What wrong I  am doing?

I never had issues with cloudflare/sentora.

You need to understand that cloudflare require you use their DNS. So you can't use both as it will be irrelevant. Setup all your dns entries with cloudflare and don't use sentora DNS. That will be fine.

I have dns manager activated on sentora so there are nameserver pointed to my ip address on that. 
I have my name server pointed to my sentora dns.

What i did? 
I removed my NS from sentora DNS manager. ( I also added NS of cloudflare on sentora in dns manager, that even didn't work.
I pointed my NS from domain registrar to Cloudflare NS . 

It didn't work. 

I didn't remove my ns from sentora dns manager. 
I only pointed my NS from domain registrar to cloudflare. 

It didn't work. 

How to achieve it then? 

Should i completely remove DNS manager for my particular website from sentora?

it works fine when you point dns to cloudflare NS. Did you wait for DNS propagation? It could take 24-48 hours and it never happen in blip du to DNS being cached.
