I have a server on port 8085 (my pc - I use Ubuntu 16.04). There are also Virtualbox with installed Windows 7. I have an internet connection in Windows (it is possible to open google.com etc) but there is no connection to localhost. For localhost:8085 in Ubuntu everything works perfectly but for the same adress in virtual-machine doesn't work. 
I tried to modify Settings->Network and put there bridged but there is the same problem.
How is it possible to access it?
