USER network mode can't register to consul

[nhanct]

I'm using USER mode network with calico and try to run mesos-consul but
I see the logs:

INFO[0218] Syncing services finished. Stats, registerd: 1 (failed: 0), deregister: 0 (failed: 0).
but can't find the service on consul

HOST network mode is ok

Can you show more logs? It should contain information what is registered. There is a chance healtchceck is not passing so service is not available.

I tested with HOST network mode and see it works as expected.

Could you post Minimal, Complete, and Verifiable example of marathon application JSON so I can test it? What versions are you using (Marathon, Consul, Marathon-Consul)?
