I can't play online

Currently what I have

Graphics: Nvidia Geforce RTX 2060

Processor: Intel Core i7 2.3 GHZ

1ms refresh rate

Screen: 240hz

1920x1080 – resolution

In this latest update, v.1.5.3, I can't play online. There have been other updates that haven't let me play either; I was able to play the previous one, v.1.5.2.

I don't know if anyone has any ideas on how to fix these problems. I've had them since the day I bought it. It's a disaster on EA's part.

Let me know.

Thanks.
