XDC apothem masternode setup failing

Hi team,
I am trying to setup a apothem master node locally by following the docker installation.
The node was able to fetch blocks till #30,309,618 after this node has stopped fetching blocks(attached screenshot from https://apothem.network/#stats)
Image description

In the node logs I could see unknown ancestor error(as attached in the screenshot):

Can you please guide me to resolve this issue.
