Why can't some sites open through my home modem?

Question

Computer networks

At home, some sites are not loaded through the Promsvyaz m200a modem. I thought that the problem was in the laptop: the hosts file, viruses. But the pages are not loaded from all devices connected to the home point. What can be wrong?

Answer 1

You try to enter the site through an anonymizer, for example daidostup.ru, it opens - it's in the provider's network, since the symptoms are similar on all devices.
