error acquiring .net

### Describe the bug.

Sorry, I'm a lousy programmer and I can't find a solution through search engines

I use vscode to write my webapi project. Yesterday, I was able to get code prompts. But today, it doesn't work for some reason. I don't know why. I restarted vscode but it still doesn't work.

I found the following content in the output, but I can access https://dotnetcli.blob.core.windows.net/dotnet/release-metadata/releases-index.json through the browser

>Error : (WebRequestError)

What I have tried

I configured the settings.json of the .NET Install Tool, but it didn't work.
> "dotnetAcquisitionExtension.existingDotnetPath": [
{
"extensionId": "ms-dotnettools.csharp",
"path": "C:\\Program Files\\dotnet\\dotnet.exe"
}
],

In addition, I tried to uninstall the C# code writing plug-in provided by Microsoft's official website in vscode a long time ago. I found that it was effective, but it didn't work after a few days.
