Hi @Az-Bin,

2.70.0 is not the latest Azure CLI(2.75.0).

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.

Here are some similar issues that might help you. Please check if they can solve your problem.

• "az login" error from PowerShell #26860
• Certain az commands not working in PowerShell #27087
• az login fails in Powershell from different networks - error Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it' #26962
• az login failed today #28701

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

Solution 1:

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 2:

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

Reference:

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

Solution 3:

Looking at the error message, it seems like the issue is at the Network socket layer causing the connection failure. You seem to have a proxy / firewall in your corporate network. This is blocking the connection to the url login.microsoftonline.com due to the proxy authentication.

Could you please test it from a different network and check if you still face the same issue? You can probably check with the internal network team in your org who can whitelist the URL on that proxy or bypass it.

btw I think the proxy should be "http://de001-surf.zone2.proxy.allianz:8080", but after setting it as env. variables still doesnt work, I can run az login outside of my virtual machine , and with same email I could login, only within virtual machine does not work.

This issue isn't related to the CLI. Please contact your admin for help setting up the proxy correctly.
