How to fix "Can't manage CORS on this resource. Please select another storage resource." error.

Question

How to fix "Can't manage CORS on this resource. Please select another storage resource." error.

Andrew Mundt 0

I am trying to use my own data in Azure Open AI. In the Chat Playground, In the the "Add data" window, I set up a new Azure Blob Storage (using the East US regional, Azuer blob Storage as the primary service, and Locally-redundant storage as the Redundancy). Once I select my new Azure Blog storage resource, I get the message that I must "Turn on CORS." However, pushing on that button results in the message "Can't manage CORS on this resource. Please select another storage resource." After researching this (https://learn.microsoft.com/en-ie/answers/questions/1851604/unable-to-upload-files-to-azure-openai-using-own-d?page=1&orderby=Helpful&comment=answer-1631864#newest-answer-comment), I added a CORS rule of * for Allowed origins, checked all 8 options under allowed methods, * for Allowed headers, * for Exposed headers, and 3600 for max age. After saving, I refreshed the Azure Blog storage resource options back in the "Add data" window, but get the same error. What do I need to do to get this to work?

Thanks!

Hi Andrew Mundt

Greetings & Welcome to the Microsoft Q&A forum! Thank you for sharing your query.

I understand that you are experiencing an error when trying to use your Azure Blob Storage with Azure OpenAI, can you refer this https://learn.microsoft.com/en-us/rest/api/storageservices/cross-origin-resource-sharing--cors--support-for-the-azure-storage-services?source=recommendations

Log in to your Azure Portal and navigate to your Blob Storage account.

Go to the Settings section and select CORS under the Blob service.

Allowed Origins: * (This allows all origins; you can specify particular origins if needed for security). When configuring CORS, you can set the Allow-Origin to a specific URL. Https://*.openai.azure.com This means that only requests coming from that specific origin will be allowed to access the resources on your serve.

Allowed Methods: Check all methods (GET, POST, PUT, DELETE, OPTIONS).

Allowed Headers: * (This allows all headers)

Exposed Headers: * (This allows all exposed headers).

Max Age: Set to 3600 seconds or as needed.

After entering the CORS settings, ensure you save the changes.

Make sure that your user account has sufficient permissions to manage CORS settings on the Blob Storage account. If you are unable to modify these settings, check with your Azure administrator.

Clear your browser cache or try accessing the Azure OpenAI Chat Playground.

Refresh the Azure Blob Storage options in the "Add data" window after making these changes.

Return to the Chat Playground and attempt to select your Blob Storage again.

I Hope this helps you! Thank you!

When I logged in this morning it now worked. It appears that the CORS rules takes some time (more than minutes) to take effect. I suggest that there be a notification about this.
