Hi @anilsakr Find similar issue https://github.com/Azure/azure-cli/issues/21247.

Issue title	az login: Failed to establish a new connection: [Errno -2] Name does not resolve

Possible solution: It seems that you are encountering a connectivity issue when running an Azure CLI command in your QA environment. The error message you received is: ERROR: <urllib3.connection.HTTPSConnection object at 0x7ff24b791100>: Failed to establish a new connection: [Errno -2] Name or service not known.

A similar issue was reported before, where the user encountered an error message: <urllib3.connection.HTTPSConnection object at 0x7f3ed60e6490>: Failed to establish a new connection: [Errno -2] Name does not resolve when trying to log in with Azure CLI inside of a container.

The solution provided in the previous issue was to test if the container can resolve login.microsoftonline.com by running the following commands:

apt-get update
apt install dnsutils
nslookup login.microsoftonline.com

You can try running these commands in your QA environment to see if the container can resolve the domain name. If the result is similar to the one provided in the previous issue, then the issue might be related to the DNS resolution in your environment.

Please confirm if this resolves your issue.

Also wanted to mention, Actually same pipeline code and network configs are working for Dev environment even am able to deploy using MS hosted agent but when I run in QA its throwing this error. As suggested tried nslookup login.microsoftonline.com in self hosted agent, its able to resolve, below is the out put,

Server:		10.60.12.8
Address:	10.60.12.8#53

Non-authoritative answer:
login.microsoftonline.com	canonical name = login.mso.msidentity.com.
login.mso.msidentity.com	canonical name = ak.privatelink.msidentity.com.
ak.privatelink.msidentity.com	canonical name = www.tm.ak.prd.aadg.trafficmanager.net.
Name:	www.tm.ak.prd.aadg.trafficmanager.net
Address: 20.190.190.129
Name:	www.tm.ak.prd.aadg.trafficmanager.net
Address: 20.190.190.130

Address: 20.190.190.131
Name:	www.tm.ak.prd.aadg.trafficmanager.net
Address: 20.190.190.132

Is there anything we need to check on Cloud-Init Configuration?

What is the cli version by running az version? If it is indeed 2.225.0, please try to upgrade to the latest version by https://learn.microsoft.com/en-us/cli/azure/update-azure-cli

Just wanted to say I also get a similar error if the account name was incorrect, when using az storage file download-batch
I'd do an echo and check (STORAGE_ACCOUNT_NAME) is what you expect it to be.

Maybe a better error can be provided?

Running Az version 2.52.0

Agreed, I had a similar experience with the key vault, the message is not helpful to pinpoint the problem, in fact it will mislead towards unrelated issues.

[sofia-valles]

Is there any update on this issue? I'm also getting this error upon running az storage blob upload. I've already confirmed that I am referring to the correct storage account, permissions are in place and the resolving works.

[calvinhzy]

Hi @sofia-valles, can you help provide the detailed environment info? Are you also using a QA environment and what OS/terminal are you using? Wondering if any of the solutions in https://github.com/Azure/azure-cli/issues/21247 might be helpful.

Did it work for you? This is failing in our case as well. We are trying to upload a blob via Azure DevOps Pipeline.

@calvinhzy -

In our case, it is one of the Azure DevOps agent (Linux - ubuntu-latest with version 3.234.0)

Likewise - i'm experiencing exactly the same from Azure DevOps using Azure CLI 2.57.0 on build agent ubuntu-latest on 3.234.0

[Itsamirmasoud]

Experiencing the same thing when trying to batch upload to an Azure Storage account. We have 4 env, works well on 3 and fails on 1 of them.

[yusbel]

I'm receiving the same error when listing secrets from Azure KeyVault or setting new secrets. I receive this error using the portal shell and using locally the az cli after sucessfull authentication.

az keyvault secret list --vault-name "keyvaultname" -o table <urllib3.connection.HTTPSConnection object at 0x7f2cad608d60>: Failed to establish a new connection: [Errno -2] Name or service not known

Any hint? Thank you

[yusbel]

I was able to connect without error after restarting the computer
