在尝试连接到Nuget时,我得到了下面的错误,然后我无法连接:
无法加载源的服务索引 https://api.nuget.org/v3/index.json。 发送请求时发生错误。 无法连接到远程服务器 连接尝试失败,原因是被连接方在一段时间后没有正确响应,或已建立连接 由于连接的主机未能响应68.232.34.200:443而失败
我可以在浏览器上访问https://api.nuget.org/v3/index.json。

你的一个金块来源可能无法到达。
在撰写本文时,AspNetCore (https://dotnet.myget.org/F/aspnetcore-dev/api/v3/index.json)似乎有一个过期的证书或已被完全删除。
只需从设置中删除nuget源就可以解决这个问题

I had the same error message while scaffolding Identity to my ASP.NET Core MVC project. Since my connection was not behind a proxy, removing/editing proxy configurations didn't make sense. And I didn't want to delete a file or uninstall PMC either. While looking around I realized a "Clear All Nuget Cache(s)" button on Tools --> Options --> NuGet Package Manager --> General. After pressing the button I had to wait for some time for the operation to complete. After that I tried to scaffold the Identity again but it didn't work. Then I decided to restart VS and voila :)
我在Windows 10中使用docker-compose up命令在Dockerfile中运行RUN dotnet restore时遇到了同样的错误。
我已经尝试了互联网上提供的所有可能的解决方案,也一直在关注这个公开的问题。最后,在花了8个多小时后,通过遵循前面的步骤,我能够解决我的问题。
Uninstall Docker from your system Restart your system Install Docker from this link. Below is the version of my Docker Restart your system Start Docker for Windows, search Docker in the search bar in Windows. Make sure it is running. You should also go to Services.msc and make sure the services Docker Engine and Docker for Windows Service are running. At last, you must check your Nuget.config file from C:\Users\{Username}\AppData\Roaming\NuGet. For me, the content of that file was as below. <?xml version="1.0" encoding="utf-8"?> <configuration> <packageSources> <add key="nuget.org" value="https://api.nuget.org/v3/index.json" /> </packageSources> <packageRestore> <add key="enabled" value="True" /> <add key="automatic" value="True" /> </packageRestore> <bindingRedirects> <add key="skip" value="False" /> </bindingRedirects> <packageManagement> <add key="format" value="0" /> <add key="disabled" value="False" /> </packageManagement> </configuration> Hope this helps.
有些东西可能改变了你的代理设置,比如Fiddler。关闭Fiddler,然后关闭Visual Studio并再次打开它。
我有一对Windows 2016服务器,其中Visual Studio无法连接到NuGet。在尝试了几乎所有其他建议的修复(注册表更改,Visual Studio/NuGet相关的缓存清理或文件/配置更改)后,以下是我们解决它的方法。
我们有一个组策略(GPO),设置了密码,我将这些密码添加到我们的GPO密码列表中,以使其工作。

安装小提琴也给我带来了类似的问题。卸载fiddler并从机器中删除fiddler代理。config(来自Framework和Framework64)解决了这个问题。
