外网与云服务器ECS无法建立Socket连接的问题

ECS内网ip为：N.N.N.N
公网IP为：G.G.G.G

ECS云服务器上python脚本为：
……
sk = socket.socket()
sk.bind(("N.N.N.N",5126)) #绑定在"0.0.0.0"也试过了，同样不可以
sk.listen(5)
conn,address = sk.accept()
……

自己设备上的脚本为：
……
sk = socket.socket()
sk.connect(("G.G.G.G",5126)）
……

安全组规则设置为：
Capture

已经打开了端口

可是就是连接不上，是啥原因？

防火墙状态，监听应该附上截图。客户端用tcping进行端口探测时用抓包工具分析一下（wireshark）

防火墙已关闭，通过查看'netstat -ntlp'命令，确定服务已经绑定上了
