Safari constantly can't open page

I just got today a new laptop (OS is windows).
I use safari as my favorite browser but, when I installed it I couldn't access any webpage.
I constantly says Safari can’t open the page “url-name” because the server where this page is located isn’t responding.

I've tried to install different versions. I've tried to use the program data from my previous pc (where it works fine), resetting safari, but no use.
It also has not to do with proxy settings, I checked it.

But I can access to internet through every other program, Internet explorer, steam, ...

Please help me with this, I NEED SAFARI

thank you for your support everyone
