Requests to hosted agents in Foundry are timeout

[chengyuliu-msft]

I was testing hosted_agent samples here https://github.com/microsoft-foundry/foundry-samples/tree/main/samples/python/hosted-agents/agent-framework/agents-in-workflow.

I followed README file and it worked quite nicely locally, and I built images and pushed to container registry, granted reader access for Foundry project. I used python SDK to register agent in Foundry, then I clicked the start deployment, and shortly it showed running. However, when I sent messages from both playground and terminal, it did not respond until timeout.

Any tips or suggestions on how to troubleshoot and proceed ?

Thanks.

@chengyuliu-msft can you use the logstream API to check the container's console logs after you send the request to if there is any errors? https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry#view-container-log-stream

The traces showed it was timeout.
