My node was running for a while but now I have noticed that it does not sync. My height is shown as 1441300, and the real height is 1441824.
Looking at the logs in the NIS console I see:
2018-01-02 08:45:46.411 INFO skipping refresh of blacklisted node: Node [[c=#86c0e9]hachi[/c] <NBCYZ7REMOHQAASWEUDWE3NV35SU4P4XQOZC7MQQ>] @ [hachi.nem.ninja] (org.nem.peer.services.NodeRefresher a) ...... 2018-01-02 08:45:46.418 INFO skipping refresh of blacklisted node: Node [Hi, I am Alice3 <ND6RTQICHTPWUT5OV7SHVDQ42HCVUVRJKJZXDNQA>] @ [188.8.131.52] (org.nem.peer.services.NodeRefresher a)
It is not clear what it means, but I assume that for some reasons the nodes with which the server tries to sync are being blacklisted. Is this right?
If this is the case, why are they blacklisted (I have not modified anything, neither I have added any lines to a config file). How can I make my sever sync again?
