Also observed this when attempting to set up Hubs Cloud AWS for the first time today. Attempting to import an avatar pack yields two failed network requests:

• A 404 to https://<cors-proxy>.<internal domain>/<request URL>, which if followed shows a GitHub pages 404 error page
• A 403 to https://<cors-proxy>.<internal domain>/null/api/v1/avatars/undefined
