Certificate problem on 1.17 URL cesiumjs.org/releases/

Hi,
From May the 5th the certificate for this URL seems to be expired.

https://cesiumjs.org/releases/1.17/Build/Cesium/Cesium.js

Normally it redirects to: https://cesium.com/downloads/cesiumjs/releases/1.17/Build/Cesium/Cesium.js
but now the certificate issue deny this redirection.

Do you think the certificate issue can be fixed on the old URL ?
