[hbinkle]

Trying to load a fresh created cra app served using HTTPS=true from my iPhone leads to an endless loading loop.

Steps to reproduce:

1. npx create-react-app my-app --template typescript
2. ($env:HTTPS = "true") -and (npm start)
3. load app on iPhone using https://:3000

Environment

npm version: 7.9.0
iPhone IOS: 14.6

Expected behavior

app should load fine, like without HTTPS=true.

Actual behavior

endless loading loop
