 Message Code 27791
Server 'server name' has shut down the connection prematurely

The server shut down the connection unexpectedly, possibly in the middle of a response.

Troubleshooting
Ping the remote host to which you were connected. If it does not respond, it may be offline or there may be a network problem. Try again later.
Ping a local host to verify that your local network is still functioning.
Ping your local router address.
Ping a host on the same subnet as the remote host to which you were connected (if you know of one). This will verify that the destination network is functional.
Send a "traceroute" command to the remote host. This will not reveal the problem unless you know the router addresses at the remote end, but it may help you determine if the problem is somewhere along the network path. 看看能不能解决问题
原先我用IP欺骗时候也出现过类似的错误提示，但后来执行的时候加了用这些Ip的生成器就没有问题了
