Consegui resolver isso reiniciando o cluster com um CIDR diferente (estava usando anteriormente o mesmo CIDR que o host vm (192.168.0.0/16). Usei 172.16.0.0/16 e funcionou imediatamente.
Tentando usar helm no meu cluster do kubernetes. helm init correu bem, mas tentando instalar ou apenas helm list apresenta este erro.
$ helm list

Eu pesquisei por muitas horas e nada parece estar resolvendo o problema. Aqui está a informação do meu cluster:
