These extensions do work before I reset my Windows 10. But after I reset my Windows, reinstall my softwares including vscode-insider. I cannot use these extensions with Remote - SSH on the remote side. I take the screenshots.

VS Code version: Code - Insiders 1.35.0-insider (6ac87465f297a9068bf767f45d6f372fc5697de9, 2019-05-17T17:48:07.036Z)

I have been following similar issue in https://github.com/microsoft/vscode-python/issues/5676 - could it be related?

I'm having an issue getting result displayed in Python Interactive console, which also uses WebView.
It used to work in past version (of VSCode Insiders, Remote-SSH, and Python extension), but now it shows blank screen with only a title.

The Git Graph extension is using the Web View API need to make some adoption work https://code.visualstudio.com/api/advanced-topics/remote-extensions#using-the-webview-api.

//FYI @Chuxel

This is also happening for the python extension. I've verified that with insiders 1.34.0 our extension loads just fine. With insiders 1.35.0, the webview we have in our extension doesn't load the bundled javascript.

You can see it here:

This is what it should look like:

@Egamma This does not look like an extension issue as @rchiodo mentions. Git Graph is using the correct message passing pattern and has no local web server from what I can tell. This may be some sort of regression in 1.35.

//cc: @mjbvz Did something regress here in 1.35?

@bpasero I bisected this and believe the error was introduced by https://github.com/microsoft/vscode/commit/afe9a74dbf14bed2908712739d01faf48e158e69 Can you please help investigate as I am not familiar with this code. I believe the same problem also effects loading of icon images from remote

This should be fixed by https://github.com/microsoft/vscode/pull/74134. Please test using the next VS Code insiders build
