Why does my AnywhereUSB keeps disconnecting over wan?


I’m using an AnywhereUSB/5M and accessing it via the internet.
My problem is that the device keeps popping in and out from the AnywhereUSB Configuration utility, as if the connection is unstable. The connection IS stable. There’s no loss of pings, other services on the same connection work fine, it’s just the digibox that’s giving me a hard time.
The AnywhereUSB device is currently on the latest firmware. It has a static IP address and a single USB device connected to it.

I think I’ve read somewhere here that possibly downgrading the firmware could fix this? I’m really at a loss and could use some ideas on how to fix this.

Thank you!
