external endpoint fails after several days.

[matthiaspresent]

Dear SQLShark,

First off, thank you for the elaborated explanation of 'machine learning form model to production'.
I have an issue with the external https endpoint in Kubernetes. I did everything you did in the labs and it all went fine except that after several days the external https endpoint in Kubernetes fails to evoke a response. Everything in the Kubernetes dashboard indicates that it is still working, so this drives me mad.

Do you have any idea if this is a common issue with a Azure Kubernetes - ACR collaboration or something else..?

Thanks in advance.
