Add-Ons are not displaying on Marketplace in IDEA

When I tried to open the Add-Ons from my Cuba Project, the Marketplace shows nothing.

My company’s firewall setting blocks some websites, but I can open Jmix Marketplace – Jmix in browser, so it should not be the case.

Anyone knows how to resolve it.

If your network has a proxy server for internet access,
setup proxy settings as described here: CUBA Studio User Guide

If it’s not the case, please present your idea.log file (main menu → Help → Show Log in Explorer)

It suddenly works now, not sure exactly what it was yesterday.
