When I send files via the network save feature it never completes and eventually (30 minutes ish) times out.  I have an EPAX X1 and I am using the latest EPAX firmware 4.2.18 and version 1.6.1 of Chitubox.

I am able to copy files over the network to the USB drive with the Photon Network Controller without any issues so I know the EPAX X1 is working ok.
