Thank you for the reply galigos.

If you can connect to the EU and JP servers but not the NA server, then you are likely running into a issue along your way to that particular server. Unfortunately, this means that the issue arises from outside of your home network. The troubleshooting we can provide has to do with strengthening your home network (your PC or PS4 and router). As such, I'd suggest contacting your ISP and making a report with them..
