Hi xbiv2,
I've not ran a Syscoin wallet for a while now but am unaware of any network problems. Try adding these addnodes to your syscoin conf file:

If it still won't sync then your wallet could be corrupted -try restarting your wallet with -reindex, but that will take a while to finish - be patient. If it still won't sync then you can ask on the official censored Syscoin thread, but they will probably tell you to join slack, discord or some other platform before bothering to help you, if they do at all.
Good luck.
