[CentOS] NFS problem after 7.2

I just updated my fileserver to version 7.2 and got some NFS problems
after that. In /etc/exports I have the following line

/path hostname(ro,insecure)

Now that host can no longer mount that share. I get
mount.nfs: access denied by server while mounting x

Also when I do restart of the NFS server I get following in the logs
Dec 30 21:59:33 files systemd[1]: Starting NFS server and services...
Dec 30 21:59:33 files nfsdcltrack[31076]: sqlite_query_reclaiming:

(disconnected from bus)
Dec 30 21:59:34 files nfsdcltrack[31412]: sqlite_insert_client: insert

What to do?
