Had problems on this particular game for months. It can take up to an hour to log in and when playing it lags often. No other games have this problem. I contacted epic game support and they suggested static ip address for PS4 - done. They also suggested port forwarding which is also done, and we purchased a TP link powerline adaptor kit which is brilliant for all other games on PS4. The final email suggested I contact VM and check that my Ip address has no issues connecting to the following:
Second line support could not check this so suggested that I post here to see if anyone has any ideas? I'm no expert and the game is played by my 12 year old son. He is almost throwing the console out of the window with frustration as he always gets shot when it's lagging. If anyone can help it will save WW3 from breaking out!
