I have the similar/same issue since yesterday.

Each time when I log-in to the game, the server kicks me in 2-3 min. I try to ping the server and it seems the block the direct ping. I only try to random ping 124.150.157.1 and I believe it is their gateway. On the other hand, I ping Google too. The result is:
1) Ping to 124.150.157.1 w/ 50-70ms & no problem / Google w/ 8-12ms & no problem
2) Ping to 124.150.157.1 w/ 50-70ms & time out when I was kicked / Google - same
3) same to (1)

It is not my ISP problem and it seems the 90000 was caused by the server side. Please fix it ASAP. I cannot play in this situation. As a result, it will cause ppl to stop the subscription and it will include me.

Thanks.
