Apple Watch update error

Unable to update my Apple Watch series 3 to my iPhone 8plus,I received an error message not connecting to the internet although I am connected to 5G WiFi how can I fix the problem?

Maybe the watch isn't connected. Make sure both devices are connected to the same network and try again.
