My Lots Won’t Save

After creating a lot on the Sims 4 on my PlayStation 4, I’m not able to save the lot to my gallery. It always gives me an error message saying server error. We cannot process this gallery request. Please try again later. I do not understand why it says service error because I have Internet connected to it successfully and I’m able to download other peoples lots with no issue if I didn’t have the Internet connected, then that would be impossible to do.
