Hello, @EA_Atic Thankyou for you attention, seriously....
according to the article, I have tried the connective guide
1.Use a wired connection.
Yes, I did try to use wired connection but it still the same situation just like I use wireless. it stuck in the [waiting for other players] then go back to the menu.
2.Move your router.
Yes, it already the closest distance I could even tried to set up.
3.Wireless? Change your Wi-Fi channel.
I am using 5Ghz network and the channel is 149 and there are only 3 other household using this channel surrounding my search area.
I did also tried 2.4GHz network and there are still go back to the menu.
4.Other things to check
I pretty sure my connection is very stable since I could play All-out Warfare and Portal normally with my 3 other friends either Coop AI or VS players.
And I assume that wasn't the connection problem at the players court, because my 3 other friends also couldn't play Hazard Zone at all, it just keep [waiting for other players] then go back to the menu even we are the 4-man squad.
I saw some other players also appear this issue even in different platform or in PS5
Hazard Zone does not start
Can't even play hazard zone anymore? Lobbies won't start
Hazard Zone mode issue
I just casually searching about '' Could not start hazard zone '' and I found 3 article about this issue.
Maybe this is not my particular problem?
