I have tried open DNS, and resetting router, wired connection, WiFi, reboot PS4 but still not working. I downloaded UO trace software but it doesn't run because of China internet maybe. I tried with vpn too but still doesn't work. I can tell you that my ping is around 100 ms as I run a test on some Chinese ping test website. Can you tell me if it's the problem of Chinese internet? 

I have another problem. Earlier when I could login to EA and used to play online, it would work on online season but I couldn't play online friendlies. Or if I started it would lost connection around 70-80 minutes of match. Can you tell me what can be problem?

Thanks
