Absolutely baffled why I am getting Error: read ECONNRESET when trying a simple GET request

Long story short, I've already finished the FSJS Techdegree and before deploying my full stack app to Heroku / Netlify, I'm trying to get this project working locally on a new PC. For some reason, I cannot get the API running on this new computer. I've even gone back to the API validation course and when I try to make a simple GET request from the starter code, I am getting the Error: read ECONNRESET in the log in Postman. This is beyond frustrating because as mentioned, I had this working on an older computer. Google has not provided me much guidance on this as I know it isn't an issue with the code, but rather some sort of setting on my PC. Willing to provide any more information as necessary since I realize this is an awfully difficult issue to diagnose. Thanks so much.
