Connecting to G-Raid w/TB3 over network

I have two external Mac drives, a G-Raid with Thunderbolt and a G-Raid with Thunderbolt 3. My windows machine can read and write to the Thunderbolt, but can only briefly connect to the Thunderbolt 3. Two other external mac drives also connect without difficulty. Can anybody help?
Thanks!
