Stopped an archival node for a bit and when I went to restart the node it no longer syncs with the network and I am getting this message when checking the status: “_**Last supported block (13409875) is committed. The next block consensus protocol is not supported. Catchup service is stopped.**_”

Wondering what the issue is and how I can overcome this.
