I don't know why you showed two different configurations for blackbox exporter, or why you say "Metrics that would have been returned" - either they were, or they weren't.
It appears to be failing to connect - 120 seconds is a very long deadline. I suggest you: 1. Try making a direct connection yourself, from the same machine where blackbox_exporter is running: openssl s_client foo.example.com:443 -servername foo.example.com GET / HTTP/1.0 and/or just curl -v https://foo.example.com 2. Use tcpdump to look at the traffic between the blackbox_exporter node and the target host. If you're seeing only outbound TCP SYNs then it's some sort of firewall or routing problem. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
