It says that the connection attempt to the host "loghost" on TCP port
514 failed (AF_INET, not IF_INET - you should paste error messages
whenever possible, typos make it harder to see what's going on).

You need to test several things:

 1) does the name "loghost" resolve to an IP?
 2) can you telnet to port 514 on the loghost from the server trying to
 3) if not, can you connect to port 514 from the loghost itself? If not,
    make sure you have syslog-ng listening on that TCP port with a line
    something like this:
     source src { unix-stream("/dev/log"); internal(); udp();
     tcp(ip("") port(514) keep-alive(yes)); };
 4) if syslog-ng is listening on that port but you cannot connect from
    the remote host, make sure there's no packet filtering/firewalling
    between the hosts. See if you can ping between the hosts or make
    other connections like ssh or HTTP.
