Apple Watch SE 2 update fails pairing with iPhone 12 Pro Max
I am using an iPhone 12 Pro Max running iOS 26.5. When attempting to pair my Apple Watch SE 2, the iPhone forces a watchOS update during pairing. The update downloads successfully, but fails during the verification stage with the error:
“Unable to verify update — The watchOS update couldn’t be verified because you are not connected to the Internet.”
I have already tried:
- different Wi-Fi networks
- restarting both devices
- resetting network settings
- unpairing/re-pairing
- disabling VPN/Private Relay
The important detail is that the same Apple Watch SE 2 pairs successfully with another iPhone XR running iOS 18.7, without requiring any watchOS update. The watch is currently on watchOS 11.6 (22U84).
This suggests a possible compatibility or verification issue related to iOS 26.5.
