Unknown error: Error code 1

Same to me, problem occurred a few days ago

Already done the run as admin process and reinstalling the game

Look people i contact with ea and he says that we need to try that https://help.ea.com/es-es/help/faq/opening-tcp-or-udp-ports-for-connection-issues but if not works do uotrace and contact YOU with ea  

Hi, I can play now. What I did is watch this video that is not my channel and there is no announcement, it is the solution https://www.youtube.com/watch?v=8K0FyHBwiy4  where is it? You need to open cleanUp.exe and I think it will work and if it will do the same steps as it. If you need more help, post your problem here if I can help you, I will help you. Good day!

Have a good game!
