Try systemctl status syscoind to see if the daemon is actually running.
If not, take a look at the debug.log in the data directory cat /home/syscoin/.syscoin/debug.log
Be aware that you need to reindex both the vps as well as Syscoin-Qt when updating to 4.1.3.
If you haven’t updated the node already, then update it to 4.1.3 and then reindex.
If the node is running 4.1.3 already, I suggest removing everything except for the syscoin.conf file in the data directory of the masternode, and then starting it again.
