Getting blank screen

I’m trying to archive a digital publication (built in Scalar), but when using ArchiveWeb I’m just seeing a blank white screen. It does seem to be scanning and archiving page assets, but I can’t see anything in the viewer during archiving or in ReplayWeb. I’ve tried both Chrome and Firefox and get the same issue.
