Server Error whenever I'm upload to my personal gallery

I WAS ABLE TO RESOLVE THE ISSUE OF NOT BEING ABLE TO UPLOAD BUILDS TO THE GALLERY!!!

ISSUE:
Received “Server error. We could not process this gallery request. Please try again later.” when trying to upload builds to the gallery since 07/21/2025. (with/out CC and/or mods, on/offline. old backups/ new saves, DLC/no DLC.. Nothing worked!! However, I was still able to upload sim households with/out CC) .

SOLUTION:
1. Go to C:\Users\Documents\Electronic Arts\. You should see a folder labeled The Sims 4
2. Rename that folder to The Sims 4_backup and move it to the desktop or a place you can quickly access. 
Now your Electronics Art folder should be EMPTY.
3. Repair Game by going to EA APP > The Sims 4 > Manage > Repair
4. WITHOUT ADDING ANY FILES, load the game and start a new one.
5. Once your sim is loaded into their home, go to the world map screen > find an unoccupied lot (any world) > select BUILD
6. Go to the gallery and find a RESIDENTIAL LOT (preferably with 1-3 packs, but base game is fine also!) and load.
7. Once loaded, save to the gallery. Check the gallery to see if the build is there.

IF THAT WORKS…… WITHOUT EXITING OR SAVING THE GAME……..!!!!!!

8. Navigate to your folder from earlier named The Sims 4_backup 
9. Open up your NEW The Sims 4 save file folder. Copy and paste 1 OR 2 save files, NOT THE WHOLE FOLDER! from the Sims 4_backup to the new The Sims 4 save file folder.

I suggest using your MOST RECENT save and a backup from when you notice the problem or the past 1–3 months.

EXAMPLE:

Most recent save:
Slot_00000888.save, Slot_00000888.save.ver0,
Slot_00000888.save.ver1 Slot_00000888.save.ver 2, and etc

Another/ Old save
Slot_10000123..save, Slot_10000123.save.ver0,
Slot_10000123.save.ver1, Slot_10000123.save.ver 2, etc. 

10. IN-GAME.. Exit to Main Menu > Select Load Game> Choose your oldest save file and repeat the steps of loading a lot (this time try one you have built/ decorated. NO EA homes!) If that works…

11. Go back to the main menu and select your most recent save file (the one that gave you the issues) and repeat the same steps with the original lot you wanted to load.

 If you can upload it now, YAYYY!😁

12. EXIT GAME (without saving)
13. NAVIGATE TO YOUR Sims 4_backup AND Sims 4 folders!
14. WITHOUT DELETING OR REPLACING!!! DRAG AND DROP ALL TRAY FILES! (NOT FOLDER!!) FROM BACKUP TO THE NEW FOLDER.
15. Clear your cache and reload the game. Open the save file of your choice and try to upload your build again. (if prompted to overwrite.. Select Save New) and boom :)
16. You can begin adding your Events, game config, options, user settings, etc, back in to restore your original settings.

DO NOT DELETE NEW SAVE FOLDER! Drag and drop the same as the tray files!

I did as you asked above, it didn't work🤕

i have serios issues with the gallery IT NEVER WORKS!!!! i have tried deleting and redownloading prayer nothing works all i would like is to share my builds/sims with the community and download and use the build from the community but cannot because the gallery never works now it saying my library is full but its all stuff from maxis........im so confused this is the best and worse game ever....... lots are hard to place or will not place at all from the library or gallery again i have memory i have downloaded it 3x this week seem to git worse because now it saying library is full and server issues i give up

I've been having trouble with a lot I want to save in Sprucederry Grove. I'm not even trying to upload it, just save it to my own gallery. I have it set to a Residential Rental, not sure if that makes any difference. Not only do I get the error message, a few days ago after failing to save the lot, I turned on my PS4 and found that my game had crashed. When I opened the game, I received a message saying that my saved data was corrupt. Fortunately, that message was in error and my saved data is fine.

My sims 4 isn't allowing me to upload my household to my gallery on my xbox one. I have cleared the cache, unplugged and plugged in my xbox, restarted my xbox, uninstalled and reinstalled sims, my wifi is fine, and done a power cycle, my birthdate is correct and my account isn't child locked, my xbox and game are up to date. and it still isn't working. How do I fix this?

For the past two days I have been trying to upload a build to the gallery and trying to just save it to my library. But it keeps popping up with an error message. Saying "Server Error". I have checked my internet connection, cleared cache, I exited out of the game and went back in, and I am now repairing the game. But I feel like this isn't going to work either. Any suggestions?

I am also experiencing this same issue. 

I have been trying to save my builds to my own personal gallery and I get a pop up saying there has been a Server Error. I have done everything clear my cache, deleted everything to free up space in my gallery, even uninstalled my entire game and reinstalled it. I have even unlink and relinked my xbox to my ea account. Yet I still get the same issue. The game is also running extremely slow and I have a great connection and have no internet issues. It is getting quite annoying after spending all this money on this game and I am not even able to play it due to all the issues I a having. 

Started having this same problem, please if anyone has found a fix. 

Can you share what worked for you? I haven’t been able to upload to the gallery for months 🥲
