Does not synchronize the wallet v0.8.6.2-g85f303d-beta . Here is my configfile

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcport=57284
gen=0
server=1

addnode = 51.15.162.24: 57288
addnode = 93.115.61.74: 51583
addnode = 35.158.7.235: 49778
addnode = 79.99.0.252: 57288
addnode = 85.230.85.100: 57288
addnode = 76.29.29.254: 57522


What could be the problem?
