I’m having trouble deploying my OpenAI model to a web application through Azure OpenAI Studio. After I finish setting up my model and move to the deployment step, I keep getting an error that says it can’t fetch locations. The error also shows a 404 status code message. This happens right after I choose my subscription from the dropdown menu. I already checked and my Azure resource group has a valid location assigned to it, so I’m not sure what could be causing this issue. Has anyone else run into this problem when trying to deploy models to web apps?
This location fetching error hit me during my first Azure OpenAI Studio deployment - spent hours on it! Turns out it’s a regional availability issue. Not all Azure regions support OpenAI deployments, so you get a 404 when the service tries to fetch locations that aren’t available to your subscription. Check if you’ve got access to supported regions like East US, South Central US, or West Europe. You can verify this in the Azure portal under your OpenAI resource’s available regions. If your current region isn’t supported, just create a new OpenAI resource in a supported region. Fixed my deployment problems instantly.
Same thing happened to me three weeks ago on a client project. The 404 location error can hit when your Azure OpenAI quota’s maxed out or there’s a service outage in your region. Before diving into permissions and registration fixes, check the Azure Service Health dashboard first. I burned hours troubleshooting the wrong stuff when it was just a service disruption. Also, if you’ve got multiple Azure subscriptions linked, try switching to a different one temporarily - sometimes the Studio interface gets confused. The error message usually doesn’t tell you what’s actually broken.
Hit this exact issue last week! My Azure subscription wasn’t registered for OpenAI service properly. Check your subscription settings - make sure Microsoft.CognitiveServices is registered as a resource provider. Mine showed ‘not registered’ and caused the 404 when fetching deployment locations. Took 5 minutes to register, then everything worked.
Hit this same issue yesterday - switch to incognito mode first. Azure Studio sometimes caches bad data that breaks the location dropdown. Also check if your OpenAI resource is in a preview region that recently lost support. I’ve seen this 404 when regions get downgraded without warning.
Had the same issue about two months ago with Azure OpenAI Studio. That 404 error when fetching locations is usually a permissions problem with your subscription, not the resource group location. Here’s what fixed it for me: make sure your account has Azure OpenAI Contributor role at the subscription level, not just resource group level. Also try a different browser or clear your cache completely - the Studio interface gets stuck with old auth tokens that don’t have the right permissions. If that doesn’t work, use Azure CLI instead of the web interface. It’s way more reliable for deployments.
