Intellij IDEA 2017.1.5 安装插件时连接超时

Question

我的 IDE 有问题。它不想更新或安装任何插件（但它允许我注册我的许可证并浏览每个插件）。它给我一个通知：

Connection failed (Read timed out). Please check network connection and try again

我查看了一个日志文件，这里有什么：

有没有人遇到类似的问题，知道怎么解决的？

Answer 1

^{张贴 CrazyCoder 的评论作为答案，因为它对我也有用。}

解决方法是在外观和行为→系统设置→更新[=25]中取消选中使用安全连接选项=] 设置部分 window:

Answer 2

设置--外观&行为--系统设置--更新--使用安全连接（不勾选） enter image description here

Answer 3

运行在 IntelliJ 2020.3 中遇到同样的问题。原来 IntelliJ 的默认代理设置是“无代理”。我把它设置为自动检测，问题就解决了。如果您在防火墙后面（例如公司环境），请检查此项。

Answer 4

检查您是否使用 VPN。这可能会导致连接出现问题。关闭 VPN 可能会有帮助。
