Running .net core app through VS cannot access network assets

We have written an core 2.1 api for Docker. The app is able to ping the internet but it is no able to access my local network. I am, first, trying to run it through visual studio.

All settings for docker are at their defaults. The subnet mask matches my network subnet mask.

How do we get local network access for my docker app? We cannot ping a server on the network (or connect to sql server as well).
