OpenRemote composer.openremote.org dead?

Sorry for the dramatic post but I see other posts with no replies or assistance.

The domain https://composer.openremote.org/ has a certificate problem which probably causes the whole thing not to work.

The problem seems to be a 404 on reset.css which causes the designer not to show.

So are the community servers no longer being maintained?

As a result, I’m stuck.

Please help ASAP
