Server Error uploading to gallery/library

For over a week now, every time I try to save my builds to the gallery, a server error message pops up. "Server error. We could not process this Gallery request. Please try again later."
I’m currently trying to rebuild some of my worlds, so I removed any kind of cc or mods I have in my game because it has lead to issues in the past. Literally moved it out of the Mods folder into a backup folder on my desktop. So, it can’t be that. 
I tried the whole technique with renaming your Sims 4 folder, starting the game to force it to make a new one, and then putting back the old Tray, Cache and Saves folders twice. That didn’t work either, so I figured I just don’t have space in my gallery. Removed everything I had in my Tray folder and that didn’t work either. I repaired the game several times and it didn’t do anything. 
As a last resort, I created a new game to check if my save was corrupted. No dice.
The only possibility left, according to google, is that some file in my game is corrupted and is messing with the saving process. I’m really not sure what could’ve triggered it, because it started before the update (really hoped it would maybe fix it but no) and I didn’t do anything different than usual. 

I attached a photo of the error message. Can anyone help? I really don’t want to lose these builds because I'm actually really proud of them :/
