Hi @xxiong2021,

2.70.0 is not the latest Azure CLI(2.72.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

Please check your DNS settings and make https://login.microsoftonline.com/ reachable. You can test if you can directly reach login.microsoftonline.com with Python:

python3 -c "import requests; print(requests.get('https://login.microsoftonline.com/').status_code)"

• az login failure: [Errno -2] Name or service not known #20797 (comment)
• az login failure: [Errno -2] Name or service not known #20797 (comment)

Solution 2:

It is a proxy error, please check your proxy configuration.

Caused by ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 405 Method Not Allowed'))

Reference:

• "az login" error from PowerShell #26860 (comment)

Solution 3:

Please make sure Python can access public internet through your proxy. This can be verified with:

& "C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2\python.exe" -c "import requests; print(requests.get('https://login.microsoftonline.com/').status_code)"

To check the settings of your proxy,

• If proxy is configured via HTTPS_PROXY or HTTP_PROXY environment variable, please make sure it is pointed to the right URL by running ls env:.
• On Windows, this can also be found in Control Panel -> Internet Options -> Connections -> LAN settings -> Proxy server -> Advanced

• "az login" error from PowerShell #26860 (comment)
