Azure Function Issue Loading Function App in 'Code + Test'

Question

Hi,

When going into a running function app and selecting 'code + test' , the function app code is not loading. Other colleagues are also having the same issue. This has only started happening recently, I've tried loading other function apps and all are the same. Does anyone know why that would happen?

Thanks.

Kate Robson Thank you for posting this question in Microsoft Q&A. I would like to confirm if you see the issues only with Code + Test option or saw errors like "Azure Functions Runtime is unreachable". Have you already followed docs: https://learn.microsoft.com/en-us/azure/azure-functions/functions-recover-storage-account to troubleshoot the issue?

This error might be due to Azure Functions not able to reach storage account and since you saw similar errors with other Azure Functions, validate if there are network rules or firewall rules modified when connecting to storage accounts. Hence, follow the suggestions in the doc:

• If function app is deployed to your App Service Environment (ASE), validate the correct network rules to allow traffic to and from the storage account.
• If the storage account firewall is enabled, then check if it is configured to allow traffic to and from functions. For more information, see Configure Azure Storage firewalls and virtual networks.

Also, check App is behind a firewall and make sure traffic is not blocked. Please check and let me know if it helps in resolving your issue. Feel free to add a comment for any additional questions.
