I cannot see your linked graphic.
The help in this FAQ for data upload resolves most issues. It includes troubleshooting advice. https://galaxyproject.org/support/loading-data/
Specifically, 1) Check the compression (and uncompress as needed), 2) make sure uncompressed data is < 50 GB for most datatypes and < ~25-35 GB for BAM datasets, and 3) know that interrupted FTP transfers can be resumed.
