如何解决将存储库从Gitlab.com传输到自托管的私有Gitlab实例时出错？
我正在尝试将存储库从gitlab.com迁移到新安装的自托管Gitlab，该文件位于公司内部基础结构-gitlab-private上。我当时在gitlab.com上工作，但是现在我们已经在本地安装了自己的gitlab，所以我不想导入新的仓库，而是要导入所有项目。
我尝试按照以下步骤操作https://docs.gitlab.com/ee/integration/gitlab.html
将我的gitlab-private集成到gitlab.com中。完成所有步骤后，我们会在登录页面上看到通过gitlab.com进行签名的选项。当我尝试登录时，会弹出一个询问授权的弹出窗口，当我单击“允许”时，它会加载一段时间，然后出现500错误。
我真的无法理解这里出了什么问题。我检查了日志，除了此以外什么都没有-

注意-我的gitlab-private实例没有与外界的任何外部连接
让我知道是否有人可以提供建议。
解决方法
如果您有no external connectivity，则无法进行这种集成。
您要在此处实现的是oAuth2 SSO。为此，必须从oAuth2提供程序（在您的情况下为Gitlab.com）可以访问您的实例。此外，您的实例必须能够访问Gitlab.com进行必要的握手。
当您仅尝试迁移项目时，只需在Gitlab.com上简单export your project，然后再将其再次导入到您的私有实例上，就会容易得多。
