Our app cannot be installed through Manage Apps because of a problem in Marketplace CDN.
Example: https://marketplace-cdn.atlassian.com/files/artifact/aa8b0dc0-035e-4dfe-bdbc-c5e0807ba6f3/structure-gantt-2.4.0.jar results in 502 status.
At the moment, https://developer.status.atlassian.com/ lists Marketplace as “Operational”.
