Sub-Domain not Working with CloudFlare DNS

[apinto]

Greetings,

In Short my Problem is:
Sub Domain does not work with CloudFlare enabled. Works without CloudFlare Enabled.


Here are the details:
I'm using CloudFlare as my DNS for my Sentora domains.
Currently my Sentora subdomain is sentora.mydomain.com, working as expected.
I've created a Client account in Sentora for mydomain.com, working as expected.
In that Client account I've added a subdomain sub.mydomain.com...

CloudFlare DNS Settings:

• A - mydomain.com - 11.22.33.44 (CloudFlare ENABLED)
  
• A - sentora - 11.22.33.44 (CloudFlare Disabled)
  
• CNAME - sub - mydomain.com (CloudFlare ENABLED)
  

With the above settings, sub.mydomain.com does not work, if I disable CloudFlare it starts working.

What I've tried:

• Waited For Daemon to run and for DNS propagation.
  
• Restarted Apache.
  
• Rebooted Server.
  
• Installed mod_cloudflare (not that it should be needed, but in any case).
  
• Tweaked with CNAME and A entries (like the sentora.mydomain.com, same problem).
  

Note:
Previously I've added subdomains like this and they worked without any issue. I've cleaned my Ubuntu VPS and made a fresh Sentora Install and have setup everything according to the Sentora Guide.

Can anyone try to help me? Thank You!
