You probably need to create a .conf file and add nodes.
I'm no expert though!
That's what I ended up doing...
'twenty15.conf'
rpcuser=user
rpcpassword=v98x983wlm2lkm4908cvxlk344l3
listen=1
server=1
addnode=87.92.120.68:41141
addnode=173.255.192.134:41141
addnode=107.170.133.216:41141
addnode=108.46.179.78:41141
addnode=174.45.80.214:41141
addnode=46.165.209.144:4114
The username and password was just because because it wanted it. You can feel free to change it by getting a cat and rolling it around on your keyboard. Sometimes the wallets don't like the simple ones. You also will have no need to remember it anyway. Hope that helps
