I am also receiving this error. In my case, I have a set of reports deployed and schedules set up for each one that run the same report multiple times with different parameters. Each report is scheduled 1 - 2 minutes apart. Most of the reports run without issue, but one or two random ones fail with this crypto message. All reports are using the same datasource defined in the repository, so it is not an issue with the password being incorrect. Please advise.
