初次使用dbeaver，新建连接就说Connection refused: connect

IO 错误: The Network Adapter could not establish the connection
The Network Adapter could not establish the connection
The Network Adapter could not establish the connection
Connection refused: connect, socket connect lapse 2055 ms. /10.16.23.177 1521 0 1 true
Connection refused: connect, socket connect lapse 2055 ms. /10.16.23.177 1521 0 1 true
Connection refused: connect
Connection refused: connect

拒绝连接，是IP地址错误，还是端口被屏蔽了，检查一下。

[jcc][t4][2043][11550][4.26.14] Exception java.net.ConnectException: Error opening socket to server /192.168.197.128 on port 50,000 with message: Connection refused: connect. ERRORCODE=-4499, SQLSTATE=08001

我是这个

解决了吗
