Hi Daryl, Thank you for bringing this issue to our attention. Indeed, I am able to reproduce the error you see. More specifically, it is the mixed interval variables that are giving us trouble. We are in a period of transition currently moving our Unidata Science Gateway servers from Jetstream 1 (which will be end-of-lifed, shortly) and onto Jetstream 2. As a temporary fix while we look into this more deeply, can you possibly access these data from https://thredds.ucar.edu/? We will continue to examine this problem over the next few days.
