ios 16.4.1 (a) is not installing

I tried to install the iOS Security Response 16.4.1 (a) update and I received the following message:


“iOS Security Response 16.4.1 (a) failed verification because vou are no longer connected to the Internet.”


I’ve attempted the update on two different wifi connections and on a cellular connection. Same message.


My device is receiving/sending email, connects properly to various web pages, and can send/receive iMessages.


Has anyone had success with this update?

iPhone 14 Pro

This is related to iOS 16.4.1(a) rapid response update. I can confirm that this is the issue that most people with iOS 16.4.1 is having. I am one of them as well. I recommend that you wait for a few hours and then try again. There is nothing wrong with your iPhone.
