Q: iOS 9.3 "Unable to Verify Update" - new Firewall - what ports?

Hi,

I am getting a "Unable to Verify Update" error for iOS 9.3 update. Stating that I am no longer connected to the Internet.

I do know that I am connected to the Internet (through home wifi).

However, I happen to have a brand new Firewall. Could this error be caused by blocked ports?

If yes, what ports does iOS need?

I am seeing some blocked traffic for ports 16403, range 49460 - 49472.

Apple has reportedly pulled the update for iPhone 5s and older.

Apple has pulled the iOS 9.3 update for older devices (iPad Airs and previous, iPhone 5s and previous) due to problems with Activation. See these articles for details and possible workarounds.

A new build for the iPad 2 is now available that does not require the Activation step. A fix for the other devices is not yet available. I doubt it is your firewall but you could disable it temporarily and test.

So, I am concluding it is not my firewall. The iphone got a notification earlier that there is an update and now it is pulled.

In general, does an IPhone or iPad require any ports other than port 80?

I don't believe so, I have never had to open any ports on my firewall and my iPad and iPhone work normally.

Good to know. I don't think that I had to open ports in the past for function.
I do wonder however, what on the iPhoen/ipad is trying to get out on high ports like range 49460 - 49472. or even 60k. An app?
