Meu problema é difícil de explicar. Não consigo abrir alguns sites. Por exemplo, alguns sites fornecidos pelo Google. Eu posso abrir o mecanismo de pesquisa do Google, mas não consigo abrir o YouTube, a página de download do Chrome (o navegador). Outro exemplo é a Microsoft, posso abrir o site, mas não consigo abrir http://iso.esd.microsoft.com/
de onde devo fazer o download do Windows 10 Insider Preview. Recebo o erro "Servidor não encontrado" no Firefox e "Página da Web não encontrada" no Chromium. Posso ver que os sites estão no site Down for Everyone ou Just Me . Também posso abri-los a partir do meu dispositivo Android e outro laptop executando o Windows 8.1; a máquina que tem problema é o Ubuntu.
O que fiz até agora: desativado ufw
(firewall sem complicações), alterei os servidores DNS fornecidos pelo meu provedor de serviços de Internet com os servidores DNS do Google ( 8.8.8.8
e 8.8.4.4
).
Qualquer ideia do meu problema.
nslookup
para iso.esd.microsoft.com
NOTE downforeveryoneorjustme.com disse que o site está ativo.
$ nslookup
> set debug
> iso.esd.microsoft.com

;; connection timed out; no servers could be reached
Quando eu mudei as configurações do meu servidor DNS, isto é o que eu fiz: Eu abri um terminal e eu digitei network-admin, vá para a aba DNS, eu removi a configuração padrão (127.0.1.1) e adicionei 8.8.8.8
e 8.8.4.4
depois disso, vi que não consigo me conectar aos sites e mover as coisas de volta, então agora estou usando 127.0.1.1
novamente. Eu quero mencionar que eu consegui me conectar ao Youtube, ouvir algumas músicas, e o YouTube parou novamente (provavelmente só para mim, já que meu Android estava funcionando bem com ele) e agora está de novo.
