Proxy Credentials Popup not showing

[maxbec]

Issue Type: Bug

Hey guys,

i entered a proxy in settings.json http.proxy.
I don't want to store my credentials in clear text so after pressing turn sync service on with github i wanted to wait for the credentials popup for proxies. But it is not coming. Instead there comes an error: Proxy authentication required.

How can i fix this?

Thanks for the report. Basic proxy authentication for extension-host requests was implemented in 82104a3: a 407 Basic challenge now opens the proxy credential dialog, and remembered credentials are stored encrypted. This can be closed as completed. The fix shipped in 1.92.0.
