Eclipse "bake" plugin cannot be installed

I use now the latest Eclipse (2025-12 / 2026-03)
I haven' access/reponses to the esr link for installing bake.

The Link returned "Bad Gateway":
https://assets.esrlabs.com/eclipse-plugins/com.esrlabs.eclipse.bake.updatesite/

Is it not supported anymore?
Is there another possibility to install the PlugIn?
