Disconnecting from CHEL

Last two days when I’ve been playing CHEL 3v3s I have randomly been disconneted every few games. I have tries troubleshoptikg my internet connection which has not helped unfortunatly. Everything else is working fine on my Network, only EA connection gets disconnected. Everytime it happens I check the playstations connection and it has been fine.

Any idea what might be causing this and what I can do to fix it?
