How to fix Error Code EC:10000 or EC:10500 in EA app?

Hey,

I have been trying for four days now.. When I open EA it says it can not connect to servers, then sends me to log in. I try to log in, but only get this message:

Something went wrong

Due to the effects of a particularly stubborn issue, you will need to log in again.

Errorcode: EC:10500

I have tried any tips from the sims forum and my internet deliver.

Things I have tried:

- Delete the app, and download again.

- Everything to do with firewall

- Restarted my router

- Change my internet connection and server

- Tried to use my mobile internet.

- I have been in contact with the company that I deliver internet subscription, they tried and failed.

- I have been in contact with Telia (yes did see a post here earlier that Norwegians have this issue with Telia) and they where unaware of the problem and could not fix it.

Please help me with this issue, I need my chill sims weekends now in a very stressful time in my life.
