Greenbone-nvt-sync not sysnc

rsync: [Receiver] failed to connect to feed.community.greenbone.net (45.135.106. 143): Connection timed out (110)
rsync: [Receiver] failed to connect to feed.community.greenbone.net (2a0e:6b40:2 0:106:20c:29ff:fe7f:d2ae): Network is unreachable (101)
rsync error: error in socket IO (code 10) at clientserver.c(139) [Receiver=3.2.7 ]

I’ve tried syncing many times. But it still can’t sync. How should I fix it? Note: I’ve installed Greenborn 2 times with the same IP.
