I'm attempting to deploy an ASP.NET web app using Azure by setting up continuous deployment through Github.

I went through the steps of creating a new web app on the Azure portal, connected it to my Github repo, and deployed it. On the Azure side of things, everything runs successfully and I'm told that the deployment worked. But when I navigate to view my app, I get a blank page, it doesn't work.

Upon checking my Github repo for the app, I noticed a failed deployment error. The app builds fine, but the following error log appears:

I'm pretty new to Azure but I currently have another deployed app on my subscription that works fine, so I don't understand why it's saying "No subscriptions found for ***"

It's also confusing to me that this error appears on Github even though on Azure it says the deployment was a success (even though my app does not work). I really don't get what's going on.

• First of all, please include your GitHub Error Log in the question itself instead of using an image. Secondly, please include your GitHub Actions Workflow file so we can help you debug it. – akseli Commented Mar 13 at 0:31
• @Kyle Hochdoerfer How do you authenticate GitHub Actions to Azure using Basic or User Identity? – Aslesha Kantamsetti Commented Mar 13 at 5:04
• @Kyle Hochdoerfer Check your secret variable in GitHub settings and make sure to paste the correct SubscriptionId. – Aslesha Kantamsetti Commented Mar 13 at 5:06
• @akseli Understood. I've edited my question and added the error log and the Github Workflow file – Kyle Hochdoerfer Commented Mar 13 at 15:41
• @AsleshaKantamsetti When I set up the web app using the Azure portal, I enabled CD to deploy using Github Actions, and then selected my repo on that page. Is that what you're referring to? Sorry, still new to Azure And for the SubscriptionId, you're saying to check the Action Secrets page on my repo and make sure that the subscription ID secret matches the subscription ID from my app, correct? – Kyle Hochdoerfer Commented Mar 13 at 15:53

2025-03-12T20:27:03.5562068Z ##[error]No subscriptions found for ***.
2025-03-12T20:27:03.8902139Z ##[error]Login failed with Error: The process 'C:\Program Files\Microsoft SDKs\Azure\CLI2\wbin\az.cmd' failed with exit code 1. Double check if the 'auth-type' is correct. Refer to https://github/Azure/login#readme for more information.

The above error occurs because an incorrect subscription ID is passed when GitHub logs into Azure for deployment through the Azure CLI.

When we create a CI/CD pipeline through the Deployment Center, we have the option to select an authentication type. In your case, it is User-assigned identity, as shown below.

After linking GitHub and Azure for deployment, you can find a Managed Identity with the same name as your Web App. Copy the Client Id and Subscription Id

Goto Directories + Subscriptions Copy the Directory ID (Tenant Id).

Paste the copied values into your GitHub repository by navigating to GitHub Repository -> Settings -> Secret and Variables -> Actions -> Secrets -> Edit as shown below. Then, re-run all jobs in the `Actions` tab of your GitHub repository. This will resolve the issue.

OR Disconnect the Github in the Deployment centre of Azure Web App.

Log out of your GitHub account, click on `Change Account`, then log back in and create a new GitHub deployment.
