I cannot sync to copper?
You shouldn't need any nodes, uPnP is enabled, so syncing shouldn't be an issue, but if it is then here's some:
Nodes added for Copper Bars
addnode=184.155.117.207
addnode=129.101.180.225
addnode=71.187.248.95
addnode=68.44.77.3
addnode=69.85.86.195If you need more than that, you can use these, they are the ones I'm currently connected to and solo mining, syncing with no issues:
