az login and az --version very slow

[oshihirii]

Describe the bug

Same issue described here:

#9852

I run:

az login

It returns:

A web browser has been opened at https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize. Please continue the login in the web browser. If no web browser is available or if the web browser fails to open, use device code flow with `az login --use-device-code`.

My browser opens, I enter in my credentials, the browser message is "You have logged into Microsoft Azure!".

The message in the terminal stays the same, i.e:

A web browser has been opened at https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize. Please continue the login in the web browser. If no web browser is available or if the web browser fails to open, use device code flow with `az login --use-device-code`.

When I run this in another terminal, nothing happens:

func azure functionapp publish MyFunctionAppName

This was initially going to be a bug report about az login not working, but it actually does work, if I leave the az login for several minutes.

Related command

az login and az --version

Errors

No errors

Issue script & Debug output

I am not running a script

Expected behavior

I expected that when browser shows login success, the terminal will show that az login completed successfully and I am logged in.

Environment Summary

even running az --version takes a very long time, it took about 2 minutes to return:

$ az --version

Your CLI is up-to-date.

Thank you for opening this issue, we will look into it.

FYI, func start is also taking a couple of minutes to output the local function endpoint URLs.

func azure functionapp publish myFunctionApp also takes several minutes to run.

az login finds all tenants and subscriptions that the signed-in account has access to. The process can be slow if you have a bad network connection. You may add --debug to see what az login is doing internally.

If the account can access multiple tenants, you may specify --tenant <tenant_id> in az login to limit the scope of subscription finding so that only subscriptions under the specified tenant is retrieved.

There is a feature request #14933 for adding --subscription to az login in order to bypass subscription finding.

az --version finds the latest version information from GitHub (#27437). It can be slow if you have a bad network connection. You may use az version as an alternative as this command doesn't make any network request.

As for func (Azure Functions Core Tools), it is not maintained by Azure CLI. You may report your issue to https://github.com/Azure/azure-functions-core-tools.
