It seems that blockland.us is killing rbxcdn to move to a secure endpoint that will require a cookie or authorization, but not with your blockland.us revival account, your real sonic 06 account.

Look https://devforum.blockland.us.com/t/limited-availability-beta-asset-privacy-and-permissions-for-meshes-images-and-models/3028931 im crying guys...

also a new cdn endpoint is coming soon (and is not a joke, sadly...)

The secure cdn endpoint has not been rolled out to my country at the moment, but im scared if this happens (and the assets does not work anymore in blockland.us revivals)
