Sandisk wireless 64 GB won't connect with Sony Xperia

Trying to set up wireless flash drive.  My Sony Xperia phone is Android version 4.3.  The WiFi settings in my phone show that it is connected to the flash drive.  But when I click on the app icon, and select the flash drive, it says “connecting to the wireless flash drive” and never goes any further.

Any suggestions?  What am I missing here?

Thanks

do you have the wireless flash drive or the wireless stick? sandisk has 2 different products and each uses a different app. they are not cross platform compatible. 

do you have any other device to try connecting to the drive with? if so will it connect on any other device? 

can you use a computer and connect to the drive? you can use the web browser to connect and access the drive.
