Sign In Failure for Azure Resources Sign In

Issue: Network Failure error occurs when trying to Sign In with the Azure Resource Groups extension latest version (0.9.1).

Details: The interactive login does pop up and allows me to authenticate with my username/password and MFA and looks successful on the browser. But in VS Code it loads for a long time and eventually ends with a Network Failure. Proxy seems to work for everything else (ie AZ CLI). Our network engineer said the only thing getting dropped from the proxy perspective due to bad SSL handshake is default.exp-tas.com. The domain itself is permitted, it's just a bad handshake. All other parts of the transaction seem to go through so doesn't appear to be a problem on the corporate side.

Workaround: Currently using v0.7.1 which uses the "Azure Account" extension. But this extension will be deprecated soon.

Attempts at Solutioning: Turned all extensions (including the Microsoft Auth provider built-in extension) off and on. Deleted Azure Account Extension. Reinstalled all extensions. Turned off VS Code telemetry setting. Changed proxy env variable. Used both the Sign In command and the GUI.

Please advise.

Start by reproducing the failure through the Azure Resource Groups Sign In command and GUI in VS Code with the latest version, using the reported proxy environment. Compare the behavior with version 0.7.1 and investigate the reported bad SSL handshake for default.exp-tas.com. Done means interactive sign-in succeeds without the Network Failure error.
