Unable to Verify Update. The Watch OS update couldn’t be verified because you are not connected to the internet.

The 7th try was the charm for me on WiFi. Reset the Apple Watch to factory defaults, followed by a hard reset before staring the pairing process. Also did a hard reset on the iPhone prior to starting the pairing process. Then updated as part of the pairing process. Note that my first 6 attempts using this approach all failed. For some inexplicable reason, it succeeded the 7th time.

Each attempt took around 1.5 to 2 hours. Not fun. Process is definitely messed up. Seem like the only resolution is persistence - keep at it until it works.

Mine is finally installing this morning. I did a unpair/re-pair last night and still no luck so this morning I plugged my phone into the charger next to my iMac, plugged the watch into its charger next to the phone and iMac, and redownloaded the update(I had deleted the update from my system last night) and after 45min(download time) it went right to verifying and then installing. Not sure what the change was or if it is the Trifecta of Apple but it's working.

Hi

I suggest that you try again with your iPhone connected to Wi-Fi, not Mi-Fi.

I can speak to that suggestion. Same issue occurs.

Same here. Been trying for hours.

Cool! Take your wins where you can get them 😉 Glad you got it working.
