Hi again to all & @EA_Ataashi
I was of the opinion that this problem was caused by the Princess skin crate as this is when the problem 1st occurred on my Xbox. If you read my earlier posts, you will see that I overcame the problem by changing back to an older skin and rebooting the console. This worked and I had no further problem last night. Reading through the posts, I noticed some were saying the problem appeared before the Princess crate was unlocked so I decided to try again early this afternoon (Aust) and found that I came up with the same error 2593. Tried several times without success so I changed Leia back to the princess skin & tried again with the same error coming up plus a new one "your friend is just finishing a match. Try again. Error 2889" That one seemed ridiculous as I am a lone player and was not trying to join any group. However, I continued on noting some had tried Xbox one network settings with/without success. I tried all the network tests and didn't find a problem. So I went to the network advanced settings and manually changed to an alternate port, tested the game with the same error coming up. Went back to Network settings/advanced/change port and selected automatic. Resumed the game and was able to get into a match without any problem and with the Princess skin loaded.
What I am suggesting in a "long winded way" is that you try:
1. Changing Network port selection if that doesn't work change back to Automatic port selection.
2. Do what I did initially - go back to an old Leia skin, quit the game, restart your console & relaunch the game.
3. It may also be a Sync problem so delete your local Saved Game file on your Xbox and try again.
Since this appears to be only an Xbox problem, it may have been caused by a recent Xbox update. How many of you are in the insider program?
EDIT: Played 4hrs tonight without any problems
