How to get through to VM (Vagrant + VirtualBox + Mac OS X)?

Question

virtual box

Good night friends!
There is Mac OS X Sierra + Vagrant + VirtualBox. Configs for VM are created via PuPHPet. Everything worked, today refused. Stupidly there is no ping to VM. Tried reinstalling Vagrant/VirtualBox, restarted the host, didn't help. At the same time, vagrant ssh from the directory with the active project (VM) works with a bang.
UPD #1: ping 192.168.56.101 is trying to crawl through the external network :( At the same time, the router settings have not changed, i.e. the problem is definitely not there ...
Tell me how to solve it?

Answer 1

There was an IP conflict, there was another machine on the network with a similar config. They smashed the IP, everything rose.

Answer 2

can you give the route of movement of packets during pings (traceroute tracert) out and in? And show what network interfaces you currently have in the system.
