@blackbird71 Thank you..
I just changed my DNS and it worked well
but i wounder, changing my DNS will harm my internet connection??

@leocg yes, all opera sites and services
i tried all browsers but all i got is:

hello..
i'm facing a weird problem with opera sites and all services from opera
i cant enter opera sites i dont know why but it worked with my friends..
some of you will ask me: so how you're posting this topic
okay my answer is: i'm using a vpn to reach opera sites..

thank you:)
