Iphone not showing up in devices/ Unable to sync local files anymore

[Will_96]

My device (an iPhone 4) use to appear in my devices fine, but I have change to an iPhone 5s and now it won't recognise it. I've tried what spotify have suggested, which was to switch the computer off and on again, and my phone, but it still isn't working. Any help?

Can you try temporarily disabling any firewall, antivirus and other security programmes on your PC then restart your iphone. It also helps if UPnP is enabled in your router settings.

I've tried this but neither of those things are working. Even when I plug my phone in it still won't recognise it.

This might sound weird, but are you definitely logged into the same account on both devices?

[Will_96]

Yeah definitely, I thought that myself but I'm signed in through Facebook so I definitely am

What operating system is your computer running and do you have any security/firewall software installed (even if disabled)?

[Will_96]

Windows 7, the firewall I have is ZoneAlarm and the anti virus is SUPERanti spyware.

Is ZoneAlarm completely disabled when you are tryng to sync (and does it have built in rules to allow traffic on port 4070?)

I did notice recently that Mcafee firewall has blocked device syncing for me.  It started, as far as I know, a couple weeks ago. It may or may not be related to OP's problem, but I do wonder if spotify changed something under the hood- maybe the port it uses to sync or something.

I'll try completely disabling ZoneAlarm
