Gallery not showing my uploads

It looks like in your game folder, your connection settings to your Profile in the Gallery are damaged.
You need to do a factory reset of the game folder.

You will lose nothing. You will have still your saves and library

Step 1. Rename The Sims4 folder to "The Sims4 old"
Step 2. Fix the game in Origin

Origin/Library - right click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.

Step 3. Turn on the game - a new game folder will be created and you will have two - one old, one new
Step 4. Check if you still have this problem in the newly created game folder

If the problem disappeared

Step 5. Delete in the new game folder following folders:
"saves" and Tray.
Step 6. Go to "The Sims 4 old" folder and copy - your "saves " folder.
Step. 7, Paste this folder in a newly created game folder.
Step 8. Do the same with Tray folder
Step 9. Copy and paste your mods and CC from old mods folder to new one.
First copy the scripts mods every time checking if game is working properly. If you have a lot of CC try 50/50 method

Step. 10. If all is OK - delete The Sims4 old folder. Now you will have only one game folder which is working properly and you will see all uploaded objects in your catalog in Gallery
