Hi
Does osinstallersetupd (OS update process) not work in the presence of App Proxy? Is it a known issue?
I have NETransparentProxyProvider App Proxy Network extension. It captures all the 80/443 port traffic but bypasses flows "osinstallersetupd" flow. "osinstallersetupd" is responsible to download installer (If my understanding is correct).
The above log shows:
My app proxy bypasses the flow:
Thanks
