--- Comment #4 from Zhiyi Zhang zzhang@codeweavers.com --- This is probably not related to wine but linux tcp stack.
Debugging this problem require network traffic to be captured. I recommend WireShark.
A possible cause would be Linux TCP timestamping. You can try "echo 0 > /proc/sys/net/ipv4/tcp_timestamps" with root access to disable timestamping temporarily and see if it helps.
