Actually it is really weird; apparently on my phone (Android app) I can access the 2nd driver intermittently, but not all the time.
Could it have anything to do with not being able to access the drive from several places at the same time (if it does, I haven’t been able to nail it down yet).
Also make sure that both are configured to use different external ports.
If you’re using AUTOMATIC configuration on the MBL, your router will be able to tell you which ports are in use.
If you’re using MANUAL configuration, you need to make sure the ports are unique, and that your router is correctly configured to forward to the correct IPs.
The Connection Refused message can come up if both are using the same port – the router will send the requests to the wrong one which will refuse to allow the connection.
The devices are both set to Automatic - shouldn’t that avoid the problem?
Yes, it should, as long as UPnP on your router is functioning correctly… You should be able to look in your router’s configuration pages to ensure that the router is assigning unique ports to each MBL.
