I can not say how thankful I am. Steve offered his help and I gave him admin panel and FTP access to my website. It took him some time but he could figure out the problem.

After 1 hour of investigation. I have found that your HOSTING is denying our update notification script. I have disabled it manually in your theme. It is working properly now….
You may ask them to fix it or there might be some extra settings at your HOSTING account.

How incredible is that? I don’t quite understand (yet) what the actual issue was, but I can confirm it is working perfectly now. So what ever I will have to check with my provider, I will tell them 
THANKS STEVE! Appreciate your fantastic support.
