    We are experiencing the same issues with WestUS2 region.  About 2 weeks ago we are now not able to install Log Analytics and Insight extension with servers that are onboarded with AzureArc.  This was working seamlessly but now i have a ticket open with the Azure team that's going 2 weeks now.  I have provided logs and screenshots but they are not able to resolve our issue.  We have our Arc environment using private endpoints to send communications through our ExpressRoute.
