MongoDB auth issue in Dokku

When i run MongoDB dokku plugin, it does not work with my NodeJS app. Also dokku mongodb:list does not work. It throws MongoError: auth failed docker

It can be fixed by setting proper locals:

 sh -c "echo 'LANG=en_US.UTF-8\nLC_ALL=en_US.UTF-8' > /etc/default/locale"

RSA Host Key has been changed.

Solution for RSA host key for <ip_address> has changed and you have requested strict checking:

Method 1: Remove keys

ssh-keygen -R <server_name>

(or)

ssh-keygen -R
