Hello everyone, We are facing a ver similar issue to the one explained above, but with the "small" difference that none of what has been suggested worked for us... Let me share some background info: network connection has been working flawlessly between the mac Pro and the iPhone for months, until we moved to a new office. From that day onwards, it stopped working. The problem is the one explained above: when we click on "connect via network", nothing happens (connection is not established). We can work around that by using the "Connect via IP" option, which works well until we reboot the mac or the iPhone's IP changes. Then we need to open Xcode again and perform the "Connect via IP" again - which is in fact a no-go for us since we use this set up for test automation. We've tried everything: We did our first attempt on the network level: we can see that there are multicast message exchanged (and replied to) between the two devices. The thing is, after the initial query by the mac, and the response from the iPhone, nothing else happens. But, anyway, it seems like it's not a multicast problem... Regarding STA-to-STA communication, from the configuration perspective there doesn't seem to be any problem either. And the fact that the initial multicast messages are actually sent seems to support that theory as well. In terms of configuration, we've tried everything: Unpair and re-pair mac and iPhone Uninstall all "development" apps on the iPhone Reset the iPhone to factory settings Unfortunately, none of these worked... So: does anyone have a hint that could help us? Thanks in advance, Marc
