If you're running on a Linux system, you could try changing the
default TCP timeout by changing /proc/sys/net/ipv4/tcp_syn_retries or
/proc/sys/net/ipv4/tcp_keepalive_time depending on what stage you're
getting stuck at. Although this would be a platform specific hack and
would affect other applications too.
