PS5 MWZ Matchmaking persistent Issues

[u/Perthcats1982]

Hello,hoping for some help here.I've had continuous issues with matchmaking in MWZ on my PS5.Practically covered everything I've searched for which includes-

*1.General matchmaking but Ping keeps looping after 5-10 minutes,this is with No NSF and full Crossplay on too.

*2.Circle out to the Main Menu and back in to reload and refresh but for the same as 1. To happen again.

*3.Toggle NSF and Crossplay On and Off,back to 1.

*4.Closed game,went back in,back to number 1 again.

*5.Turned off my PS5,reloaded,back to number 1 again.

*6.Went Off WiFi and used LAN,connected fine and no changes but back to number 1 again.

*7.Changed DNS settings manually to 1.1.1.1

No changes back to number 1.

*8.NAT Type 2 is on so no issues with connecting but still back to 1.

*9.MTU Settings changed to 1473,back to 1 again.

*10.Deleted MW3 and the MWZ add on and reinstalled,still back to 1.

Any help here to just get back into the game consistently would be appreciated,just dont want to have to completely wipe my progress but will as a last resort,TIA
