For out of sync issues, which most likely are due to time changes or NTP sync issues, you must correct the system time and perform a manual sync up through the UI.

For certificate expiry issues, you must install a valid certificate and perform a manual sync up through the UI.

For a node that has been down for more than six hours, you must restart the node, check for connectivity issues, and perform a manual sync up through the UI.

Could be a certificate issue, import and trust the Local cert of that node into the admin node.

Is the "sync" button available to you under the "Deployment" tab? If yes then you can check that node and then try to sync it up. If that does not work then you will have to deregister the node and re-register it. 

Hope this helps!
