snapshot having issue restoring

hi. I'm trying to do a restore from one site to another using snapshot.

I am getting the following Gateway error:

'Gateway Time-out

The gateway did not receive a timely response from the upstream server or application.'

What can I do? I need to get this live tomorrow.

I'm trying to move a snapshot from http://www.politicalshop.com to http://109.73.231.173/~polit688

thanks,
