I am having the exact same issue and it started 4 days ago.
I have tried every solution listed in all the forums for 2002 errors and nothing works. I can log into EU/Japan servers fine
If you are willing to let me play this game for free, i can divert those funds into WTFast and play your game fine.(Actually with more lag.....)
Please find a solution to this. After all we pay a monthly fee............
