Avatar Autosetup Hung on 'Uploading Results'

On fbx import, my avatar setup hangs at 99% and on ‘Uploading Results’ with this error that may be related (it prints every time I try to use the autosetup). Waited about 40 minutes on this bar for nothing to happen, no existing resources I can find on this issue. I’ve got all my FACS expression set up, cage is watertight, HumanoidRootNode exists in bone structure ect, just want some ideas as where to look next. :frowning:
