I cant install ios 17.1.2 on iphone 14

I cant install iOS 17.1.2 on my iphone 14 (128 gbs) I did all the trouble shooting but Im simply cant do get it to download. its shows a message sayin is temporarily unavailable, but at the same time, it bugs me everytime I use my phone " a new ios update is now available. please update from the ios 17 beta" that I also did and still cant get to upgrade. is someone have this type of issue?
