The error seems to be referring to "http". Is 10.250.219.87 the IP address of the Prometheus server? If so the problem is with prometheus->alertmanager communication. How have you configured Alertmanager to use TLS? Have you configured it to require a valid client certificate? If so, there's probably an error with that configuration.
