SSL handshake error with some Azure CLI commands
I am using Azure CLI in bash within PowerShell in Windows 10. I sit behind a corporate proxy. My goal is to automate the deployment and setup of Azure resources.
Some of the Azure CLI commands work perfectly fine: I can run az login, change the default subscription, list locations, resource groups, resources within resource groups and I can even run shell scripts to deploy resources like Key Vaults.
However, when I try to list the keys or secrets within a Key Vault, or create keys/secrets I get the following:
Error occurred in request., SSLError: HTTPSConnectionPool(host='xxxxxx.vault.azure.net', port=443): Max retries exceeded with url: /secrets?api-version=7.0 (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),))
The example I am providing here is for a Key Vault, but I am getting the same error with other types of resources, so I don't think the Key Vault is the issue.
When appending the --debug parameter to the command, I can see the error is coming from one of the Python libraries:
urllib3.connectionpool : Retrying (Retry(total=0, connect=4, read=4, redirect=None, status=None)) after connection broken by 'SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",),)': /secrets?api-version=7.0
I have tried the suggestions provided at:
Working with Azure CLI behind SSL intercepting proxy server,
Including export AZURE_CLI_DISABLE_CONNECTION_VERIFICATION=anycontent to disable certificate check (not recommended) and export REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt to make Python requests use the system ca-certificates bundle.
I have also tried:
export ADAL_PYTHON_SSL_NO_VERIFY=1
which is suggested in the following post:
[AzureStack] Handle SSL verification for certs not in Python root CA list #2267
But unfortunately none of the above produced any change in the outcome.
I am using Azure CLI version 2.0.60 and Python 3.

Due to you were using Windows not Linux or MacOS, please try to use set instead of export to set the environment variables in PowerShell, as below, then to run the azure cli command for Key Vault again.
set ADAL_PYTHON_SSL_NO_VERIFY=1
set AZURE_CLI_DISABLE_CONNECTION_VERIFICATION=1
And for the command export REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt on Linux, I think you can refer to the SuperUser thread https://superuser.com/questions/217719/what-are-the-windows-system-certificate-stores to run a powershell window as administrator (right click on the PowerShell shortcut and select Run as administrator to run).
However, as you said about in bash with PowerShell, it sounds like you open a bash shell session of Windows Subsystem for Linux or like Git Bash from PS: prompt, which described fuzzily that I can not understand for your operations, please post more details about it, and I don't think it's a good practice to use PowerShell with bash nested.
