Putty: O encaminhamento da porta 80 local para o host local: 80 falhou: Erro de rede: Permissão negada

Question

Na massa, eu tenho o seguinte:

• Sessão
  • hostname: username@azurecontainsersvc_mgmt.eastus.cloudapp.azure.com
  • porta: 2200
• Conexão > SSH > Túneis Localhost L80: 80
• Conexão & SSH > Chave privada de autenticação: my_public_key.ppk

Ans quando eu me conecto, ele me pede minha senha, tudo parece ótimo, mas eu tenho acesso negado. Eu tentei executar como administrador com os mesmos resultados.

Alguma ideia? Estou perdido - obrigado!

Não tenho certeza se isso é importante, mas estou tentando conectar-me a um cluster do DC / OS no Azure: link
