If experiencing a 504 error when launching an interactive course there is a possibility that the service which facilitates our course delivery is encountering server issues.
Our first recommendation is to check here https://status.cloud.scorm.com/. If you see the following status then the issue lies elsewhere and we suggest opening a ticket:
If the status doesn’t say All Systems Operational and instead shows up in yellow or red, that means the 504 error you’re seeing is tied to an issue with our course delivery service. Once that gets sorted out, your WAVE access should go back to normal without any extra steps on your end.
