Very new to all this, but I have had SS running on this very same server a while back - now when i attempt to install again, i am getting this error, even when clicking 're-check requirements':

Connection Interrupted
The document contains no data.
The network link was interrupted while negotiating a connection. Please try again.

Is this my server at fault or the installation? - I really can't work this one out.

Any help would be very grateful
