Everything worked fine for me with Trellis from june / 2015. Yesterday tried to clone a new Trellis repo, using the same bedrock site, but all I got is ERR_CONNECTION_REFUSED.
When I try to access var/log/nginx I get permission denied.
We changed the vagrant plugin to manage the hosts file. Maybe that’s the problem?
