Cant connect to ranked games

Thanks for following up. 

Have you tried any other sort of troubleshooting at all? We should try changing your DNS settings to see if that helps if you haven't already given that a shot. The DNS is like the address book your device is using to determine how it needs to reach its destination. I've seen cases where using a different DNS can help with disconnections and lag. 

To change your DNS on PS4 follow the steps below: 

1. Open up the Settings on your PS4, then go to Network. From there go to Set Up Internet Connection, and select either WiFi or LAN cable depending on what you're using.
2. Select Custom > IP Address Settings (Automatic) > DHCP Host Name (Do Not Use) > DNS Settings (Manual)
3. Enter the Primary DNS as 8.8.8.8 and the secondary DNS as 8.8.4.4 -- This is the public Google DNS.
4. Select Next > MTU Settings (Automatic) > Proxy Server (Do Not Use) > Test Internet Connection

Let me know if you're still running into any issues after you've updated the DNS. Thanks!
