Is this running?

[thddudwh]

I am using Ubuntu LTS 16.04 and VMware ESXI 5.0.0
When I send analyze , CuckooSandbox Status is always pending

How can i do?

Are you running via the docker-compose method?

If so you can check the logs to get an idea of what might be the problem: docker-compose logs

I think the best spot to look would be docker-compose logs -f cuckoo I would bet it's not connecting to the VMs
