I have tested the port 8810 on all three nodes (nxe.ddns.net, nxe1.ddns.net and nxe.suprnova.cc), and only the Suprnova node is working. The port 8810 is closed on both nxe.ddns.net and nxe1.ddns.net, so they do not work. That's the reason of problems with sync some people are having.
Double checked but ufw says they are open Could our hosting provider have them blocked?
