Hi, I've increased all the possible timeouts, but the issue remains. As another PoC, I've spun up a temporary pod with ubuntu 18.04 on our AKS cluster. kubectl run my-shell --rm -i --tty --image ubuntu:18.04 -- bash Installed powershell 7 in the pod and then registered the repository with register-psrepository -name psmodule-test-sourcelocation http://<instance>/nuget/psmodule-test This works and installs the module On a sidenote, we also have octopusdeploy running that pulls modules from proget. This also works. I'll ask our networking team to temporarily allow http traffic to proget. To test if this issue is caused by ssl or the inverse proxy as a whole (traefik). If it's the latter, then I guess we eliminated all possible steps on this :)
