Quickstart App Issues: Failed to create tunnel connection after running `npm run start`

After successfully running the scafolding command when creating a new feature, I pasted the url from my terminal and was able to create an app.
I then ran:
npm i
npm run start

I ended up getting the following error - Creating tunnel connection [FAILED: Failed to create tunnel connection.]

When I go to my local browser I see the following:
“Hello, your user_id is: still loading. Let’s start building your amazing app, which will change the world!”

I’m able to see my user id when I check the preview in monday.com where my feature lives. Am I missing something in my .env?
