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.

在我的情况下，我有Fiddler运行，改变了我的代理设置

转到%appdata%\NuGet\NuGet.config 修改这一行: < packageSources > <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft sdk \NuGetPackages\" /> . <add key="Package source" value="https://api.nuget.org/v3/index.json" /> . < / packageSources >

在Windows 7上测试

步骤1:打开命令窗口(运行cmd) 步骤2:如果TLS 1.2被禁用(添加注册表项)，执行以下命令启用TLS 1.2支持:

"HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v DisabledByDefault /t REG_DWORD /d 0 /f /reg:32 reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v DisabledByDefault /t REG_DWORD /d 0 /f /reg:64 reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v Enabled /t REG_DWORD /d 1 /f /reg:32 reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client" /v Enabled /t REG_DWORD /d 1 /f /reg:64

你需要在Nuget中添加代理设置。配置文件。有关详细信息，请参阅此链接:Nuget配置部分和Nuget代理设置。

值得注意的是，.net核心SSL身份验证存在一个可能导致这种情况的错误。禁用他们最新的网络堆栈实现，为我解决了这个问题。

你可以永久地设置它，或者使用以下命令启动你的应用程序:

DOTNET_SYSTEM_NET_HTTP_USESOCKETSHTTPHANDLER=0 dotnet ...
