@EA_AljoI opened every PS4 and NHL port. I will test if it works better in game tomorrow and let you know how I did.
I hope that I did the port forwarding correctly and it works. Last time I opened ports in NHL20, I think I missed the part where I should have set Static DHCP to my PS4. Now I did and lets hope it works.
Only problem is when I try some online port forwarding checker like canyouseeme.org, it says that the port is still closed. Idk if I did something wrong, but if I did, I don't know what is the problem.
But anyways, I'll see how it works tomorrow!
