自升级到v2Traefik代理以来，Portainer不再显示图标

问题描述

自升级到Portainer v2后，图标突然不再加载。我仍然可以访问Portainer（由Traefik代理），但是经过一些测试，我注意到只有/会被转发。如果给出路径，Traefik将抛出404错误。这是一个问题，因为Portainer从例如加载字体。 /b15db15f746f29ffa02638cb455b8ec0.woff2。

在Github上有一个与此有关的问题，但我真的不知道该怎么处理：https://github.com/portainer/portainer/issues/3706

要使Traefik能够转发路径以便Portainer可以加载图标，我需要做些什么更改？

解决方法

您可以尝试刷新DNS缓存吗？在Chrome浏览器的“ chrome：// net-internals /＃dns”中进入网址栏，然后按Enter。然后点击“清除主机缓存” 然后刷新您的门户页面

我注意到还有Portainer的阿尔卑斯版本。

切换到该（image: portainer/portainer-ce:alpine）后，这些图标似乎再次起作用。我不知道普通图片有什么问题，但是现在可以解决。

PS：我曾尝试在Traefik上使用Access-Control标头，但这无济于事。我想这与Portainer的代码本身有关。
