Resolution
1. Make sure connectivity between DS-Client and DS-System is reliable
2. Check firewalls settings
3. Assign the DS-System user right to access the storage location
4. Adjust TCP Socket Buffer: DS-User/Setup/Advanced tab, Category: Comunication > parameter > TCPSocketBuffer. Set to a bigger value (multiple of the default one) OR limit the upload speed from DS-User/Setup/Bandwith Throttle... to a specified value based on the ISP upload limitation
5. Set the WAN port to full duplex
