Custom Question Answering Project is gone
Happen on today, our CQA project could not be loaded and connected. We have tried to access the Language Studio or Microsoft Foundry, all could not find the project with the following display:
the one highlight with yellow is the project that disappear, when click on it, it show Deployment not found:

Hello pipi
Greetings! Thanks for raising this question in Q&A forum.
This usually happens when the underlying Language resource (or the specific CQA project's deployment) got removed, moved, or the resource got migrated/re-created under Microsoft Foundry, breaking the link between your project name and its deployment. Since it worked yesterday and broke today with no changes from your side, it is most likely a backend resource or migration issue rather than something you configured wrong.
Here is how to troubleshoot and recover it step by step:
Step 1: Check the Resource Still Exists Go to the Azure Portal and search for your Language resource (the one tied to this CQA project). Confirm it still exists, is in "Succeeded" provisioning state, and hasn't been deleted or moved to a different resource group/subscription.
Step 2: Check Resource Region and Endpoint Open the resource and note its Region and Endpoint URL. Then go to Language Studio / Microsoft Foundry and make sure you're connecting using the same region and endpoint — sometimes a UI refresh defaults you to a different region where the project won't show up.
Step 3: Verify the Project via REST API Use the Question Answering REST API to list projects directly:
GET https://<your-resource-name>.cognitiveservices.azure.com/language/authoring/query-knowledgebases/projects?api-version=2023-04-01with your subscription key in the header. If the project shows up here but not in the Studio UI, it confirms this is a UI/Studio display issue, not actual data loss.
Step 4: Check the Deployment Status Directly For the specific project, call:
GET https://<your-resource-name>.cognitiveservices.azure.com/language/query-knowledgebases/projects/<project-name>/deployments?api-version=2023-04-01This tells you whether the deployment itself still exists on the backend, even if the Studio shows "Deployment not found."
Step 5: Redeploy if Deployment Is Missing If Step 4 confirms the deployment is genuinely gone but the project/knowledge base data is still present, you can redeploy it via Language Studio (Deploy knowledge base) or via the REST API deploy endpoint. This recreates the deployment without losing your Q&A pairs, since those live at the project level.
Step 6: Check Activity Log for Any Automated Changes In the Azure Portal, go to your Language resource → Activity Log, and filter for the last 24-48 hours. Look for any delete, update, or migration operations that may have been triggered automatically (sometimes Azure performs backend migrations to Foundry-based resources without obvious notice).
Step 7: Raise a Support Ticket if Data Is Truly Missing If the REST API also shows the project/deployment as gone (not just a UI issue), open a support ticket immediately referencing the resource name, project name, and the timestamp it was last known working. Backend migration issues like CQA-to-Foundry transitions have caused similar disappearances for other users recently, and Microsoft support can often recover the project from backups if caught quickly.
