Howdy @apsteger,

We've seen issues like this before when folks are using the CLI behind a VPN or proxy. Please checkout the following troubleshooting steps, and let me know if you're still encountering this issue: https://github.com/Azure/azure-cli/blob/dev/doc/use_cli_effectively.md#working-behind-a-proxy

This was happening to us until we entered these at the CLI:

export HTTPS_PROXY="proxy.server.com"
export HTTP_PROXY="proxy.server.com"

I'm also encountering an issue where "az login" hangs in Visual Studio Code (v1.36.0) when running in a Powershell context.

When I run "az login" it starts my default browser (Edge), I then select my user account (@Hotmail) after which the browser just sits there with the loading animation. The VS Code window also never returns or timeouts from "running Powershell command".

If possible I would like to be able to use VS Code as my editor for my Azure CLI scripts but I'm not sure what is going wrong.

Thanks @marstr , I'll give it a try.

I'm going to close this for now, but I'll be happy to re-open if more information comes to light.

@tommysundling, I'd also try messing around with the troubleshooting guide.

I'm also facing this issue and it hangs wither AFTER I do my 2-factor auth and the login windows in the browser stays at the progress bar screen or it says you are login in and moves on to the Azure CLI homepage. In either case, there is no further output on the Powershell Windows, even with --debug enabled. I've made sure that I am logged out before attempting another login, too. The last line of output, even with --debug enabled, is:
Note, we have launched a browser for you to login. For old experience with device code, use "az login --use-device-code"
