没有互联网接入的Websocket连接（Ubuntu）

Question

我有一个Spring Boot应用程序，它实现了一个Websocket服务器（SockJS）。

只要主机应用程序的Ubuntu机器具有Internet访问权限，我就可以将客户机连接到本地网络上的该服务器。

我拉我的WAN网络路由器上插入的那一刻，服务器会删除所有WS连接，也不允许新的。客户端将报告错误代码2000'All tr​​ansports failed'。正如我在插上WAN电缆背部和路由器再次拥有互联网接入，WS连接，重新开始工作一旦

服务器将抛出此错误。我已经在Netgear和TP-Link的多个路由器上试过了。

我已经尝试在ubuntu下手动设置网络接口设置，但这没有帮助。

任何想法可能会造成这种情况？

Answer 1

我好像你必须设置一个静态的IP，否则系统会尝试根据线鲨鱼，它没有找到，只是没有连接到达成DNS发现服务预期的IP。

Answer 2

只是固定的同样的问题，添加一行到服务器的hosts文件，somethink像：

appsrv 192.168.1.15
