SSH Debina9 (DigitaoOcean) + MacOS?

Добрый вечер!
Случилась беда. Создал сервер на Debian9.4 на DigitalOcean, загрузил SSH ключи. При попытке зайти на сервер по ssh с MacOS возникает ошибка
ssh_exchange_identification: Connection closed by remote host
Если подключаться с другой машины под управлением Linux, то заходит без проблем.

sergey@aspmbp ~/.ssh $ ssh do2 -vvvvv
