Mysql PyCharm，通过vpn进行远程数据库连接

我正在尝试使用SSH连接到远程数据库， 我正在使用openvpn连接到目标机器的网络

当我直接连接到那个网络时，它就起作用了， 但它不支持VPN

我的设置是：

Database URL:
  jdbc:mysql://localhost:3306
(jdbc connector, user and password are OK)

Use SSH tunnel:
  (checked)
SSH tunnel will be opened on localhost (127.0.0.1) and port:
  32443 (tried with several other high ports)
Proxy host:
  192.168.100.143 (this is the address of the target machine in the target network I'm connected to through openvpn)
Port:
  22 (default)
(proxy user and auth are OK)

(not 100% sure about these two, are they relative to the above proxy host?)
Remote DB host:
  localhost
Port:
  3306

SSH设置包括：

Database URL:
  jdbc:mysql://localhost:3306
(jdbc connector, user and password are OK)

Use SSH tunnel:
  (checked)
SSH tunnel will be opened on localhost (127.0.0.1) and port:
  32443 (tried with several other high ports)
Proxy host:
  192.168.100.143 (this is the address of the target machine in the target network I'm connected to through openvpn)
Port:
  22 (default)
(proxy user and auth are OK)

(not 100% sure about these two, are they relative to the above proxy host?)
Remote DB host:
  localhost
Port:
  3306

PyCharm尝试连接到本地主机， 如果我为本地主机mysql服务器插入mysql凭据，它将连接到该服务器（即使选中了“使用SSH隧道”）

我错过什么了吗

附言。 目标数据库是MariaDB，但我认为这不是问题所在，因为直接连接到该网络时我可以连接…

您应该使用以下方法：

jdbc:mysql://localhost:32443

关键是要使用隧道端口
