我花了最后4个小时尝试解决此问题，但没有成功。
我已按照所有说明在.test域上安装puma-dev。
然后，我运行puma-dev并按预期得到了
* Directory for apps: /Users/manuelfrigerio/.puma-dev
* Domains: test
* DNS Server port: 9253
* HTTP Server port: 9280
* HTTPS Server port: 9283
! Puma dev listening on http and https
但是，当我访问页面mywebsite.test：9280时，它会不断加载，但从不显示该页面。 我只在屏幕上看到此错误：
此页面无效 onward-web.test当前无法处理此请求。 HTTP错误500
现在，如果我转到mywebsite.test，则可以看到其中包含“未知应用程序”的空白页面。我已经在/.puma-dev中将我的应用链接了。
还有什么呢？
这是完整的日志跟踪：
