Yes port is 9334 and make sure to have "listen=1" in your .conf file! On one of my rigs I did not have that line and the wallet would not sync without it. So make sure that line is in there!
sure but
rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
server=1
daemon=1
rpcport=9334
listen=1
poolmining=false
cpumining=true
email=alicea@tlen.pl
addnode=node.gridcoin.us
with all variations of rpcallowip=127.0.0.1 (.*) and server=1 daemon=1 presence or not - doesn't work - doesn't connect
