In startMockZipkinCollector function, If I change net.Listen("tcp", ":0") to net.Listen("tcp", "127.0.0.1:0") or net.Listen("tcp", "[::1]:0"), it works normally.

I'm not able to reproduce on WSL Ubuntu 18.04 and the CircleCI tests have not reproduced this. Can you provide any information about your configuration that might be different? A 502 response indicates that something is intercepting the request, perhaps an anti-virus system with a "transparent" HTTP proxy?

@Aneurysm9 Yes, there is an HTTP proxy in my environment. Every time before make precommit, I need unset http_proxy
