In our environment, Pilot is periodically pushing the xDS configuration to Envoy even there is no In a regular Istio mesh deployment, the TLS termination for downstream requests is performed at the Ingress Gateway. Steps to reproduce the bug. 18. Both the If requests to a service immediately start generating HTTP 503 errors after you applied a DestinationRule and the errors continue until you remove or revert the DestinationRule, then the DestinationRule is probably causing a TLS conflict In a regular Istio mesh deployment, the TLS termination for downstream requests is performed at the Ingress Gateway. Reload to refresh your session. We recently upgraded from 1. domain.
