有没有人遇到过类似的问题并知道如何解决？

【问题讨论】：

看看disabling this option 是否有帮助。也可以尝试在帮助 | 中添加-Didea.connection.timeout=90000编辑自定义虚拟机选项。
禁用该选项有帮助。非常感谢！

【解决方案1】：

^{发布CrazyCoder的评论作为答案，因为它也对我有用。}

解决方法是取消选中设置外观和行为→系统设置→更新部分中的使用安全连接选项> 窗口：

【讨论】：

最新的 intellij idea v2019.3.1 中没有安全连接选项。但是重启IDE后没有出现错误。

【解决方案2】：

在 IntelliJ 2020.3 中遇到了同样的问题。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。如果您位于防火墙后面（例如公司环境），请检查此内容。

【解决方案3】：

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

【解决方案4】：

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