Why does the Facebook app work fine on an iPhone connected to Deco, but not on a Mac using a web browser? The Mac is connected by both wifi and Ethernet. Disabling the Mac's wifi connection doesn't solve the problem. Nor does disconnecting the Ethernet cable and using only the Wifi connection. On the Mac, I get a "Server Not Found" error. I've read that this might be related to IPv6, but I can't disable IPv6 in the Deco app.
