There are some issues with this service for now, applications traffic may not be routed through the proxy and may end up using another IP (hypervisor's IP) instead. We are investigating.
EDIT 09:21 UTC: The issue should have been fixed. Your applications might need to be redeployed if the issue persists. We continue to monitor the service.
EDIT 13:11 UTC: We didn't see any other issues with the service, the issue is now resolved.
