@leocg @blackbird71 @yanta
I want to thank you all for support, and I have new updates it may help you to solve my issue.

I tried a VPN programme and when I used it I was able to access to all these sites like addone.opera.com, opera download page, etc...

So if the VPN make it work.. what would be blocking this access without VPN ??

PS. my friend in same my country KSA has opera and working smoothly

What about network, ISP, government?

Can your system find the IP of those sites?
