Estou usando o Ubuntu e desenvolvendo o site usando o cakephp3 e hospedando-o em uma instância do Amazon AWS. Antes tudo estava funcionando bem, mas agora, ao conectar a AWS através do terminal, ele apresenta este erro: ssh_exchange_identification: read: Connection reset by peer , que também não consegue se conectar ao FTP do FileZilla, recebendo Error: Could not connect to server .
Eu verifiquei em ssh -v no terminal do sistema sua saída abaixo:
