Why does it keep kicking me out of the lobby after every single game?

After every single match it kicks me out of the lobby saying something about network problems but my internet is working fine. I know it’s working because I have done the network test on the PlayStation. It says it’s working well. I go into a game and then it disconnects with no penalty. Get back immediately into the lobby and played against a demo. And then I load into another match then it tells me that I disconnected from the host giving me the penalty. It’s becoming annoying.
