解决方案是，参考如下链接，

问题概述
当使用VScode连接远程服务器时，往往需要使用Remote-SSH这个插件。而该插件有一个小bug，当远程服务器网络不佳时容易出现。

在控制台会出现下述语句：
Resolver error: Error: XHR failed at y.onerror (vscode-file://vscode-app/d:/Microsoft%20VS%20Code/resources/app/out/vs/workbench/workbench.desktop.main.js:77:1261)

解决方法
懂了报错的原因，那就可以从中找出解决方法。即手动在本地下载安装包，然后手动传到服务器端。这样是可以解决这个问题的，虽然不是很优雅。

在服务器端，进入下面的目录，获取commit id。

$ ls ~/.vscode-server/bin
flive@flive-virtual-machine:~/.vscode-server/bin/704ed70d4fd1c6bd6342c436f1ede30d1cff4710$

在这里，我的commit id就是flive@flive-virtual-machine:~/.vscode-server/bin/704ed70d4fd1c6bd6342c436f1ede30d1cff4710$

手动下载出问题的包（tarball），注意下面的COMMIT_ID要替换成自己在上一步得到的commit id。

稳定版下载链接：https://update.code.visualstudio.com/commit:COMMIT_ID/server-linux-x64/stable
内测版下载链接：https://update.code.visualstudio.com/commit:COMMIT_ID/server-linux-x64/insider

如我的稳定版链接就是：https://update.code.visualstudio.com/commit:2ccd690cbff1569e4a83d7c43d45101f817401dc/server-linux-x64/stable

下载后会得到一个vscode-server-linux-x64.tar.gz，将其通过sftp等方式传到服务器上。路径：~/.vscode-server/bin/COMMIT_ID/vscode-server-linux-x64.tar.gz

在服务器端进入该路径，解压。

$ cd ~/.vscode-server/bin/$COMMIT_ID
$ tar -xvzf vscode-server-linux-x64.tar.gz --strip-components 1

重新使用VScode进行连接。
