我目前正在旅行所以我无法控制代理设置我希望这不是问题。但我已连接到城市周围的3或4个不同的WiFi点，所有这些都会产生相同的错误。当然，如果我无法下载
的安装文件，那么我甚至无法管理离线安装，这意味着我无法手动安装和下载证书（除非有办法下载这些证书）与我下载安装文件的方式相同。）
任何帮助都将不胜感激！
您好vijchti，
感谢您在MSDN论坛上发帖。
>> WebClient 在 中填写 span> 'https://aka.ms/vs/15/release/installer'
'无法连接到远程服务器'
- 'https://aka.ms/vs/15/release/installer' .
根据错误消息，它是由远程服务器无法正常连接的代理设置限制引起的。

最好的问候，
Hello all,
I've been struggling with this problem for a while now. When I try to install visual studio via vs_community.exe, the installer always returns the error "Unable to download the installation files".
The relevant logs are here:

What's strange is that I can manually download the installer if I navigate to https://aka.ms/vs/15/release/installer from chrome. So I added it to the --OfflineFilePath argument. The result is the same error with this log:

I'm currently traveling so I don't have control over proxy settings where I am, so hopefully that isn't the issue. But I've connected to 3 or 4 different WiFi spots around the city and all of them produce the same error. And, of course, if I can't download the installation files then I can't even manage an offline installation, which means I can't manually install and download the certificates (unless there's a way to download those the same way that I downloaded the installation files).
Any help would be appreciated!
Hi vijchti,
Thank you for posting in MSDN forum.
>> WebClientfailed in 'https://aka.ms/vs/15/release/installer' with 'Unable to connect to the remote server' - 'https://aka.ms/vs/15/release/installer'.
According to the error message, it is caused by proxy setting limit that remote server can't connect well.
For the latest documentation on Visual Studio 2017, see Proxy Authorization Required on docs.microsoft.com. This error generally occurs when users are connected to Visual Studio Online through a proxy server, and the proxy server blocks the calls. Visual Studio Online is used to keep the user signed in to the IDE.
Please have a try to whitelist the following list to unblock all sign-in scenarios in Visual Studio:
◦*.windows.net
◦*.microsoftonline.com
◦*.visualstudio.com
◦*.microsoft.com
◦*.live.com
Then try the following Ping, to check if you could connect to the download server:
The above shows that the network is well-connected, or if it shows any time out error message, it means that the your network can't connect to the resource server, in this situation, how about finding another machine without any proxy setting, refer to Create an offline installer for Visual Studio 2017 to make an offline installer with full resource, copy the files to your computer and perform a VS 2017 installation then.
