Hey there! I’m glad It’s looking helpful so far. Well , your error message suggests that you haven’t come as far to the mongodb side of the steps yet. You need to make sure that you can create an ssh connection with the USER and the PRIVATE KEY that you have provided for the mongodb compass.

I don’t know your level of experience , so I might be suggesting something way below you , but If you can successfully do

ssh user_name_at_target_server@mongodb.ser.ver.ip , then you should not be getting that error when you give user_name_at_target_server as the user , mongodb.ser.ver.ip as the SSH Hostname and pick the correct private key , which is the file name id_rsa in .ssh folder . That is , if you have no ssh configuration (.ssh/config file) for the server you are trying to connect , in which case you might have another username or another private key file other than the default id_rsa. I often see people confusing their local username and the username on the target machine.
