How do I fix a Sims Delivery Error?

I haven’t been able to play online because I keep getting a Sims Delivery Error. Does anyone know how to fix this? 

This is what I’ve tried so far:

I have onedrive turned off. I use Norton for an antivirus and have the game added to exceptions. I moved my mods folder out and deleted the localthumbcache.package, but it didn’t change anything. I repaired the game and cleared the cache too. I also ran the EA app as an administrator. 

I’m not sure what to try next. I’d appreciate any advice!
