Hello Geonmo, Indeed, you are not the first person to report this. There was a bug in the way we treated scripts that computed the checksum (as opposed to doing so natively) that returned a response gfal did not like. This will be corrected in 5.5.3 which is coming soon. So, you should stay with 5.5.1 or earlier for now.
