kex_exchange_identification: Connection closed by remote host – CPanel

I’ve wanted to connect my share hosting with ssh. So I generate an ssh key in the ssh action of cpanel and authorized it. Then I’ve downloaded the private key and drop it in the ./ssh folder of my MacBook.I’ve used this code to connect my host.

ssh -p 2083  username@host IP

but I got this error:

kex_exchange_identification: Connection closed by remote host

How can I solve my problem?

    I run into a similar case with a small computer I have in my desk. What I did to debug the issue was to run sshd -t, which runs the sshd daemon in debug mode. This command reported that the permissions of my keys were invalid. All I had to do then was to go in the folder where the keys are stored and issue chmod 0600 <your_ssh_keys>.
    Maybe the action you run generated things with the wrong permissions too.

    I got this error when using docker command with remote host

    docker -H ssh://user@server compose up

    after some digging i found on my remote server in auth logs (/var/log/auth.log) this:

    Aug  8 14:51:46 user sshd[1341]: error: beginning MaxStartups throttling
Aug  8 14:51:46 user sshd[1341]: drop connection #10 from [some_ip]:32992 on [some_ip]:22 past MaxStartups

    This lead me to change MaxStartups settings in /etc/ssh/sshd_config. After restarting ssh service everything worked like a charm.

    I had same problem and it was happend as I use ProxyCommand in ssh config file. In my case the Host was not defined correctly which then caused the same error!
