Page not found

When I try to access my assets from at assets.adobe.com I get: "Page Not Found We can't find the page you're looking for. View your files or browse your apps and services. It worked fine yesterday. It happens with all files. Viewing the network tab of dev tools I get 500 Internal Server Error for the following url: https://scproxy-prod.adobecc.com/permissions?resource=https%3A%2F%2Fcc-eu1-prod.adobesc.com%2Fapi%2Fv1%2Fassets%2Fb08421… and in the response tab: {"message":"Authorization failure - Request ID: f41a8fe0-2a5f-11e6-a7c3-515156d46bd7\n"}

I tested with different browsers and in private modes.
