iPhone software update fails

I am trying to update my iphone17 software to IOS 27, but it gets stuck at requesting update for a really long time. But after that it will show a pop up saying “Software update failed”. And I did try to update IOS 26.7 too but it ended up showing the same thing as show in the screenshot. My storage is definitely enough for the update and I tried restarting my device too. I have been trying to update these updates for a while now and it shows the same pop up. How do I fix this?

I had to use WiFi. It suggested to use it instead of cell data but looking at your screenshot I don't see WiFi. Also the time of day may be am issue as everyone is updating to iOS 27.

Trust me when I say I wish I hadn't upgraded to iOS 27. Siri demands you confirm your calls and then it will pause and stop responding and never dials the number.
