According to Macrumors, this is not a surprising move from Apple because the company usually stops signing old iOS versions a few weeks after releasing a new iOS.
This is seen as part of Apple’s efforts to help users update the latest features and ensure device security. Previously, the company also locked the iOS 17.3.1 sign.

In addition, in recent years, there has been little reason for users to downgrade to an older version of iOS, especially when they often update iOS directly via OTA instead of via iTunes. Previously, most users often downgraded iOS to jailbreak.
Currently, the latest official iOS version is iOS 17.5.1. In addition, the company is also preparing to release beta versions of iOS 17.6 in the coming weeks to add unreleased features of the iOS 17 operating system.
You can update to iOS 17.5.1 by going to Settings > General > Software Update and following the instructions.
