IntelliJ "Initialization error for 'https://start.spring.io' Check URL, network and proxy settings"

Question

Today, when using IntelliJ (MacOS) and Spring Boot to create a new project, I started this error:

'Initialization error for https://start.spring.io ' Check URL, network and proxy settings

Error message: Error parsing JSON response "

My home network has no HTTP proxy settings, just vanilla internet. IntelliJ / Preferences / System Settings / HTTP Proxy / Check Network Settings: says the network connection is OK. And the same setup worked here 2 days ago.

A browser connection with https://start.spring.io also works.

I tried to deal with this problem, but basically I found problems with the HTTP proxy settings that I don’t have (I type this without the HTTP proxy settings in the browser :-)).

Perhaps this is just a temporary problem with start.spring.io? or...? In any case, embarrassing.

Answer 1

It looks like Spring Initializr is broken for both IntelliJ IDEA and Spring Tools Suite, I reported this in the initialzr project:

Answer 2

try using http : //start.spring.io 'instead of https : //start.spring.io'. he works for me.

Answer 3

• URL- , proxy settings IDE.

• intelliJ below-

• In the IDE Open --> File → Settings → Appearance and Behavior ->System Settings → HTTP Proxy --> Select Auto-detect proxy settingsand install Automatic proxy configuration URL.

• Then we can connect to the spring initializer via intelliJ IDE
