You can use these in the console:
addnode 37.146.68.215:11931 add
addnode 23.88.164.18:11931 add
addnode 24.131.171.33:11931 add
addnode 77.47.170.101:11931 add

Or do this in the .conf file:
addnode=37.146.68.215
addnode=23.88.164.18
addnode=24.131.171.33
addnode=77.47.170.101

They made it sync for me
