According to your screenshot, I notice that your service is listening on tcp6. Based on my knowledge, if the port only provides ipv6 service, you could not use IPv4 address to access.

根据你的截图,我注意到你的服务正在监听tcp6。据我所知,如果端口只提供ipv6服务,则无法使用IPv4地址进行访问。

I notice that you use jetty container, jetty use IPv6 by default. You could allow jetty force to use IPv4. There is a good answer about this.

我注意到你使用jetty容器,jetty默认使用IPv6。您可以允许jetty force使用IPv4。对此有一个很好的答案。
