SimGuruKate and EA_Mage have confirmed that The Sims 4 Gallery will be undergoing extended maintenance that will last for over 48 hours.
Happy Tuesday SimFam! As I briefly alluded to over the weekend, we are going to be doing some extended maintenance on the Gallery beginning tonight at 11 PM PT. It may last up to 48 hours and during this time all online features will be unavailable. https://t.co/mt1KIu7UHU

This will be happening on the 4th September 2018 at 11pm Pacific, we will let you know when the maintenance will end but it is uncertain when the Gallery will be up since the team or fixing a lot of problems with it.
