Issue setting up Apple Watch S6 because it has to update

I purchased the Apple Watch S6 yesterday and so far it has been a nightmare setting it up. The pairing process works fine but the issue I have is the software update for the Apple Watch. As soon as I click update now, right after successfully pairing, I am greeted with a "checking for update" for a few seconds and then followed by an "unable to check for update" because I am not connected to the internet - baring in mind, that I am connected to wifi that is full bars and 50mbs fast. I have tried everything from resetting network settings to restarting my iPhone and Apple Watch a multitude of times, but nothing seems to work. Is there anything else that I can do?
