404 Resource Not Found

Hello @Boyedokup

A 404 (Resource Not Found) when using Azure OpenAI from clients such as Claude Desktop, Cursor, or other coding agents typically indicates that the client is calling an endpoint or deployment that Azure OpenAI can't resolve.

Could you share a few additional details?

• Which client are you using (Cursor, Claude Desktop, Continue, Cline, etc.)?
• What is the exact error message (including the response body, if available)?
• Are you using the Azure OpenAI endpoint (for example, https://<resource-name>.openai.azure.com) and the correct deployment name rather than the model name?
• Which API version is configured?
• Does the same deployment work when tested from Azure AI Foundry, the Azure OpenAI playground, or a simple REST/API call?

A 404 is commonly caused by one of the following:

• The endpoint URL is incorrect or points to the wrong Azure OpenAI resource.
• The client is using the model name (for example, gpt-4.1 or gpt-4o) instead of the deployment name you created in Azure OpenAI.
• The configured API version isn't supported by the deployed model.
• The deployment has been deleted, renamed, or exists in a different Azure OpenAI resource or region.

If you can share your client configuration (redacting any API keys) along with the full 404 response, we can help identify the exact cause.

In many cases, the issue is that the client is configured with the model name instead of the deployment name, as Azure OpenAI APIs expect the deployment name in the request path.
