@sam If the connectivity is not established with the billing endpoint at all the times this error will be seen. According to my experience if the connectivity is not established for 15 minutes or more this is reported. Also, I think free tier only provides 5 TPS.
Running LUIS image on Azure container instanse stops after sometime and getting error BillingEndpointUnavailable

Hi,
I am running below LUIS image on Azure container instance
mcr.microsoft.com/azure-cognitive-services/language/luis:latest
Service is accessible and working fine for sometime and then suddenly stops and shows BillingEndpointUnavailable .we had provided the valid API and endpint with price tier F0.
UI Error Screenshot:
Azure Container instance Logs:
Container is not in a valid state. Subscription validation failed with status 'CouldNotConnect'. Could not connect to Billing Endpoint. Please check your network connectivity. For more information please visit https://aka.ms/cscontainers-faq.
The limits are mentioned in the pricing page and should be available on the pricing tier tab on Azure portal for the resource. The containers need to be connected to the billing endpoint else the container will stop working if it does not establish a connection.
You are right . I created cognitive service with S0 pricing tier then it works fine. it was the issue with F0 price tier.
Thanks for the help
