Are you connecting with a proxy?
I have same error, i dont use proxy,
i noticed that the one who posted this error from same country,
maybe the DNS, the internet service provider problem ??
@roblourens

all thing is alright even browser or when i search on extensions in vs code but if i want download any one, it will appear to me the error message "failed to install
this appear after last update
@BeemenSameh. From your screenshot, are you trying to access this image? Can you check the "failed to load resource" url and put it here?
When you open it in browser, or run the below curl command, what happens?
curl https://ms-python.gallerycdn.vsassets.io/extensions/ms-python/python/2019.8.29288/1565127378610/Microsoft.VisualStudio.Services.Icons.Default > python.png
