Update says no connection and won't let me pair

I've had my watch for a long time but somehow got disconnected. I reset everything, updated everything and now when I try to pair my phone with the watch, the watch requires an update. I allow the update but it keeps saying I'm not connected to the internet, which I know I am. I have tried connected to the wifi and to data, but still get the error message! I've also deleted the Watch App and reinstalled, powered off, etc....still no avail! PLEASE HELP!
