title: IntelliJ "Initialization failed for 'https://start.spring.io' Please check URL, network and proxy settings"
body: <p>Today when using IntelliJ (MacOS) &amp; Spring Boot to create  a new project, I started seeing this error:</p>
  
  <p>"
  Initialization failed for '<a href="https://start.spring.io" rel="noreferrer">https://start.spring.io</a>' Please check URL, network and proxy settings</p>
  
  <p>Error Message:
  Error parsing JSON response
  "</p>
  
  <p>My home network has no HTTP proxy settings, just plain vanilla Internet.
  IntelliJ / Preferences / System Settings / HTTP Proxy / Check Network Settings: says network connection is ok. And this same setup worked here 2 days ago.</p>
  
  <p>Browser connection to <a href="https://start.spring.io" rel="noreferrer">https://start.spring.io</a> also works.</p>
  
  <p>I tried Googling this issue, but mostly found HTTP Proxy setting issues that I don't have (I am typing this w/o HTTP Proxy settings in browser :-)).</p>
  
  <p>Maybe this is just a transient issue with start.spring.io? or ... ?
  Anyways confusing.</p>
