After Ionic Serve, served app cannot detect Internet connection

Lately I have been running into a problem where I will “ionic serve” my app into Google Chrome, however the resulting serve cannot detect a connection to the internet. I am working with a few APIs so I am unable to test these without an internet connection. So far I can’t find a fix - after leaving it alone for a bit and then refreshing it will occasionally detect the internet connection again. This is very, very frustrating.

Is there anything I need to check for or any setting I can apply that will guarantee that the result from my “ionic serve” command will have an internet connection?
