¿El cliente SSH no funciona?

Cuando me conecto a través de SSH a mi servidor a través de SSH, estoy viendo algo como esto:

asd:/Users/asd () $ ssh root@47.52.32.36
Password for root@iZj6cdolljnt77ccercqzsZ:
<hangs for a while>
packet_write_wait: Connection to 47.52.32.36 port 22: Broken pipe

Pensé que podría ser un problema con mi cliente SSH, así que descargué el cliente vSSH y pude conectarme.

He intentado conectarme a través del cliente ssh en Terminal.app y iTerm.app pero ambas veces parecen colgarse antes de informar que hay una tubería rota.

¿Cómo puedo depurar por qué mi cliente SSH no se conecta pero vSSH sí?

Esta es mi versión: OpenSSH_7.3p1, LibreSSL 2.4.1

Y esta es la información -v:
