Why can I connect to mysql through ssh -> mysql, but cannot connect through a ssh tunnel, address is bound to localhost(bind-address 127.0.0.1)?

问题

I can connect to the server by ssh (ssh #ssh_user#@#ssh_host#) and then use mysql -u#db_user# -p#db_password#. Then I can use the mysql command line as usual, but I am trying to setup DBeaver so I have a client interface for it. Is it impossible to do when the bind-address is set to localhost?

SSH tunnel settings

host: #ssh_host#
port: 22
user: #ssh_user#
auth: (key)

SSH tunnel itself works, I tried it with ssh -L 23:#ssh_host#:22 #ssh_user#@#ssh_host#
