7 random 90002 error during CC fight today, Ping, tracert and internet stability OK. No problem in other content, only CC when it happens and no 90002 error in Frontline.
I dunno if i'm the only one affected, but it seems there's packet lost to the server. No freeze screen or something else, it's sudden.

Hello,

After some try with someone who live with me i'll add something on this topic. Double match CC in same time, i got disconnected but not him. We were on the same area, same internet.

If by chance someone knows how to resolve it if it's not server side, i'm taking it !
