Connecting to Remote MySQL DB over ssh with workbench

Question

I'm trying to connect to a remote DB with MySQL Workbench over SSH. The remote DB I'm trying to connect to has firewall which is private key protected (I have coverted this to OPEN SHH). I keep getting an error when I try to connect, I'm just a little confused on what is the information of the DB I should be using. I consistently see people use localhost and the DB changed intermittadely at the same point in different questions. My set up is currently that I have to connect to the server of the firewall(check) now there are multiple VMs running I wish to connect to e.g. 192.1.91.0. I have also a port set up to this on putty( I don't know if this is relevant) on localhost 5000. When I try to connect using 192.1.91.0 port 3306 or localhost 5000. I get the same error. Can anyone help. Attached is an image of the information I put into workbench

I think there are a few misunderstandings here. A firewall is not protected by a keypair. An SSH connection is. The firewall only filters network traffic using specific rules (e.g. only let it pass for enabled network ports). When you use an SSH connection you have to use the MySQL address as seen from the remote SSH connection end. That means if the MySQL server runs on the same machine as the SSH server (which is what you connect to when you use an SSH tunnel) then the address is localhost (or the IPv4/IPv6 loopback address). See my video about connection creation and troubleshooting on Youtube for more details.
