A general network failure has occurred. Verify your Internet connection and that the server you are connecting to is correct and available. If necessary, try an alternate server in order to verify your Internet and FTP connectivity.
The connection operation failed due to an unreachable host. Verify that the server or IP address is correct and try again later.
The connection was dropped or reset, possibly because the server has crashed or rebooted.
Try connecting again in a few minutes as the server may be temporarily down.
Verify that the problem is not local by trying to connect to an alternate server.
The connection failed to receive acknowledgement of data sent and therefore timed out.
Try connecting again in a few minutes as the server may be temporarily down.
Verify that the problem is not local by trying to connect to an alternate server.
The server forcibly closed the connection. This normally results from a loss of the connection due to a timeout or a server reboot.
Try connecting to the server again later.
Verify that the problem is not local by trying to connect to an alternate server.
An attempt to send or receive data failed because the connection to the server was broken. Please reconnect to the server and try again.

If a server name was used, verify it resolves to the correct address.
If using a local server table for server name resolution, check to see that it does not resolve to an obsolete address.
Try pinging the address.
If you are using a router, verify the router is up and running (check by pinging it and then ping an address outside of the router).
Do a traceroute to the destination to verify all routers along the connection path are operational.
Verify that your subnet mask is setup properly.
