2.11.1.1.2. Too many authentication failures

The error "Too many authentication failures" when connecting via SSH means that there are more than three failed authentication attempts. The reason may be that the SSH client is trying all the SSH keys available to it and offering them to the server, thus exhausting all authentication attempts.

To resolve the problem, tell the SSH client to use only the authentication credentials specified in the command line or SSH configuration file:

Add the -o IdentitiesOnly=yes argument to the connection command:
ssh -o IdentitiesOnly=yes example@example.ftp.tools
Edit the ~/.ssh/config file on your device and add this section to it:
Host *
    IdentitiesOnly yes
