@t.ho, @martinkretz – I think you’re both running into the same issue. A month ago we made core-hour billing a requirement for running Rhino on Windows Server or in a Docker container.
Please take a look at part 1. of the “Deploying Rhino Compute” guide for steps to set up core-hour billing and get a token that you can use to set the RHINO_TOKEN environment variable in the container.
You’ll need to do this even if you’re already using core-hour billing. The method using cloudzoo.json (described in earlier versions of the Dockerfile) no longer works.
