Connection Error - OV Extension Repo

Omniverse Core Platform Kit Application Streaming

Hi team,

Trying to run the sample USD Viewer container with Minikube on Ubuntu 22. Everything looks good except when trying to run the USD Viewer KIT app. Getting connection errors at runtime. Seems like it’s trying to download more extensions and a sample USD file.

Do I need to configure something extra on in the Minikube network settings? Some logs below.

I think it mostly boils down to this (and alike) errors:

Couldn't resolve host name for https://kit-extensions.ov.nvidia.com/omni/auth/api/device/authorize

Please execute curl https://kit-extensions.ov.nvidia.com/omni/auth/api/device/authorize from your minicube’s host server, if you can reach it this means that the pods inside minicube can’t for some reason, perhaps due to misconfigured DNS, if you can’t - this means your host has connectivity issues as well.

Not sure on the exact reason for your connection problems, but clearly at least one of your machines cannot get out to the required services. Please manually try to access these links as requested from each of the machines and test their external access capabilities. A lot of kit services require the ability to check on additional resources on a live Internet connection. I would at least run this application on one machine first and have it download all the required extensions as needed, before trying to apply to multiple machines.

It is an issue with my host network setup. Thanks for replying.
