Thanks! Setting overheadDataThreshold="0" does fix the issue. Without overheadDataThreshold the issue is very inconsistent:
Firefox 69.0.1 (64-Bit) on LNX and on other OS does result in the described error below. Very strange: Chrome on LNX mostly works, which means I got intermittently once got "connection closed" with Chrome. On the second retry the upload worked. Even stranger: after a successful upload by Chrome it even works with FF with the same file.
