Big files upload using S3 fail: they restart continuously

When uploading with direct transfer a +1Gb file ,

The upload starts correctly, progress shows data is uploaded,

at 100% the file is still uploading, and after a while restarts at 0.

After pausing the transfer, a new error is visible :

=> env : Intranet (S3) 

=> TARGET FOLDER : personal space

=> drive version : 4.4.2.170

NB : sur le même serveur, upload de fichiers plus petits et/ou dans le même dosser fonctionne.
