@Classic298 commented on GitHub (Jan 27, 2026):
This appears to be a deployment configuration issue rather than an Open WebUI bug.
The Problem:
Your startup probe is failing because Open WebUI hasn't finished initializing yet. Looking at your logs, the probe starts checking just ~1 second after container start — that's not nearly enough time.
Recommended Fix:
Configure your Azure Container App startup probe with more generous timing:
Also verify:
For more deployment guidance, see the Open WebUI documentation on container deployments.
@BrianArcher94 commented on GitHub (Jan 28, 2026):
Thanks for the reply, after making the changes to my container that you recommended I no longer receive a "failed startup probe" error. The container appears to pull the image and start successfully, however once it gets to a "Running" state the container terminates.
See logs below:

Looking at your logs more carefully, Open WebUI is actually starting and running successfully. The issue is that Azure Container Apps with KEDA is scaling your container down to 0 replicas due to perceived inactivity.
Notice these log entries:
"Deactivated apps/v1.Deployment... from 1 to 0"with reasonKEDAScaleTargetDeactivatedContainer terminated with reason 'ManuallyStopped'(This is not a crash)Solution: Configure your Azure Container App to have a minimum replica count of 1 instead of 0 to prevent scale-to-zero behavior:
In Azure Portal: Go to your Container App → Scale → Set "Min replicas" to 1
Or via Azure CLI/Bicep: Set minReplicas: 1 in your scaling configuration
This is an Azure Container Apps misconfiguration, not an Open WebUI problem.
And for future reference: Please do not open issues if you want to ask a question. Instead ask in the discussions or on discord.
Since this turned out to be a misconfiguration of your deployment on Azure rather than an Open WebUI bug, questions like these are better suited for our Discussions or Discord community. We try to keep Issues focused on reproducible bugs in Open WebUI itself (not installation and configuration support for deployments). Thanks for understanding!
