DLAN does not let me access EA servers?

I have the following problem: I got the TP Link AV1000 Powerline AC750 a few days ago. Everything works fine, with the DLAN. The only problem is that I can't access FIFA19's EA servers on my Playstation 4 anymore. The PSN connects without any problems, only FIFA does not go online. Can someone help me there? The reason why I bought DLAN was mainly because of the PS4 …

What does your network look like?

Router → → Dlan1 Dlan2 → Cable → PS4?

Router → → Dlan1 Dlan2 → Wireless → PS4?

Router → → Dlan1 Dlan2 → Wireless → Smarthone?

Router → Wireless → Smarthone?

Then I can help you better.
