在开始Spring Boot / Vaadin 23项目时，如何解决此BindException？

Question

当我从IDE启动Vaadin / Spring Boot应用程序时，我会收到以下服务器错误。

There was an unexpected error (type=Internal Server Error, status=500).
    Can't assign requested address

在启动应用程序之前，端口上没有任何侦听。

在Mac OS 12.3.1上运行此操作。

Vaadin 23.0.9

这太奇怪了，我什至无法想到还有什么才是有意义的。

有什么想法吗？

谢谢你！ 克里斯托夫
