Any VPN or Wi-Fi Firewall blocking the contact to Apple servers?

Can you install iOS 26.7 instead?

You can also use your computer to update your device:

If you can't update or restore your iPhone or iPod touch - Apple Support

Welcome and thank you for reaching out. 🤗

Try the following steps:

Disable any VPN connections and restart your iPhone or tell Siri: "Restart".
Learn how to update your iPhone to the latest version of iOS.
Learn what to do if your iPhone won’t update.

NOTE: According to Apple: After a software update is installed for iOS, iPadOS, tvOS, watchOS and visionOS, it cannot be downgraded to the previous version.

Need more help?

Good luck! 👋🏼😉
