-> App Service Environment isn't supported with ExpressRoute configurations that cross-advertise routes from the public peering path to the private peering path. ExpressRoute configurations that have public peering configured receive route advertisements from Microsoft for a large set of Microsoft Azure IP address ranges. If these address ranges are cross-advertised on the private peering path, all outbound network packets from the App Service Environment subnet are force tunneled to the customer's on-premises network infrastructure. This network flow isn't currently supported with App Service Environment. One solution is to stop cross-advertising routes from the public peering path to the private peering path.
