Cesiumjs.org securtiy certificate down so js won't load

Cesiumjs.org security certificate for has been down for 15 days so our map is not loading, can that get renewed?

Hi Scott,

Are you able to update your URLs to use “cesium.com” instead? As an example, Cesium instead of https://cesiumjs.org/releases/1.57/.


https://cesiumjs.com/releases/1.66/Build/Cesium/Widgets/widgets.css results in 404?


The link that you provided does in fact fail to load. Are there any specific questions that I can help you with?


Thanks for picking this up.

Problem solved. Mirroring the current release now.

Happy to help! Whenever possible, make sure that you are using the most recent version of CesiumJS. 1.83 can be found here:
