Yes I have tried Chrome and Safari, none of them worked. Im using MacOS Sierra for months now.
I went to a coffee and other places and I could access this website so I definitely think it comes from my internet connection ><. Also this specific website doesnt work either on my smartphone
Thank for your help!
Yes, that does suggestion that it is an issue with your Internet connection. I will likely suggest that the moderators move this post over to the Networking forum as you likely will get more/better help with your issue there.
In the mean time, what kind of Internet connection do you have? Cable? DSL? Fiber? Satellite? Dial-up (if so, then I feel for you
If it is a "broadband" connection (i.e. cable, DSL, fiber, etc), do you have a separate router? Or is it a combo router/modem/WiFi access point that is provided by your ISP (i.e. you rent it)? If you do have a separate router, have you tried by passing the router (i.e. connecting the laptop directly to the modem...this might require using an ethernet connection...see next paragraph)? In either case, have you tried rebooting the devices (i.e. modem and router or modem/router combo)?
Based upon your original post, it seems like you are using WiFi for the connection. If so, have you tried connecting your laptop by ethernet (if you can...i.e. if you have an ethernet port or an adapter/dongle for ethernet since most recent Mac laptops don't have ethernet but can having it "added" by way of a USB or Thunderbolt adapter)? Trying to determine if it is something related only to WiFi (admittedly, this is unlikely, but best to rule it out).
Are you using the ISPs DNS service? If so, have you tried another DNS service, if you can? For example, the Google Public DNS is at 220.127.116.11 and 18.104.22.168 for IPv4.
And last, have you tried calling your ISP? I realize that this is usually more painful that slamming a car door on your hand, but it might be something on their end that they can fix...assuming that they are aware of the issue.
