EC:10005 When i try to open my EA app on Macbook

I first had this problem a few months ago I ended up getting so frustrated that I just stop messing with it. A couple days ago I came back to it and it was working fine. I just purchased $80 worth of packs for the Sims four. Now I’m discovering that while I had the error code before I purchased the packs It is now affecting me being able to have my packs in the game.

I have tried troubleshooting. I have completely deleted all traces of the app from my computer and none of that has worked. The only way I can access the EA app is by switching between my personal Wi-Fi and my hotspot on my iPhone then it won’t let me open the EA app. However, in just a few minutes, the game will start functioning without an Internet connection despite me having one. 

I really don’t like to complain and if I hadn’t purchased the packs, then I would not have but I just spent $80 on this game. And it is very upsetting that I am continually having this problem.
