Server Error. We cannot process this Gallery Request. Please try again later.

I’m getting an error message trying to upload a residential lot to the gallery:

“Server Error. We cannot process this Gallery request. Please try again later.”

Just prior to this error the game prompted me to restart. I restarted, but now cannot upload this lot. I was able to upload the Sims family, but not their home.

I rebooted my wi-fi, signed out of the EA app, rebooted my laptop, then signed back in and re-started my game. And I’m still getting the error message. :/

Is this an issue related to the latest game update?

Edit: I was able to upload an unfinished residential lot, but still cannot upload the finished residential lot. No CC. No mods.
