It sounds like you may be having issues with your connection @lotfi_knaissi_69. I would suggest that you and your friend take a look at our Connection troubleshooting steps which you can find here: https://help.ea.com/en-us/help/faq/connection-troubleshooting-basic/

It'll take you a couple of minutes to do them all but please do take the time and do them all.

Let me know how you get on and if you want to share your UO Trace then I'm happy to take a look at how your data is being routed.
