I am having the same issue after the latest firmware update.
Have not been happy with the connectivity and downtime.
I have the router set properly (static IP) and ports forwarded correctly. However, instructions for forwarding ports were not that clear. On a Linksys EA4500 router, use single port forwarding. Set external ports to any available port, but the internal ports had to be set to 80 and 443. This took me awhile to figure out that I had to use those specific internal ports. Dashboard says ports are forwarded and connection status is connected.
Currently I can connect on my home network via wifi on my ipad. But when on the cellular network, I get the error message “the device is inaccessible; only local files are available”.
(Another gripe I had was when the WD servers went down a few weeks ago, I did not realize it until after factory resetting the device (and losing all my files).
