`az login` stuck on connecting to `login.microsoftonline.com:443`

### Describe the bug

Running `az login` is stuck after confirmation in the browser. The debug output shows it is waiting to connect to `login.microsoftonline.com:443`.

My machine is connected to the internet. All browsing works fine. I can connect to login.microsoftonline.com in my Safari browser.

### Related command

`az login --scope {} --debug`

### Errors

No error; it is just stuck waiting.
