Not connected to wi-fi
Trying to set up a previously used watch (series 4) to a different phone. Watch has been reset to factory settings. I’ve tried syncing to and iPhone 8 and iPhone 13. It shows that the watch needs a software update. After an hour of downloading the update it shows that it cannot complete because it is not connected to wifi. The phones that I have tried have been connected to wifi. Have tried multiple times with each phone. Is there something wrong with the watch?
iPhone 6, iOS 12
