Someone can pass me upgraded nodes my wallet does not sync.
Here is website for the blockchain explorer for Californium
https://prohashing.com/explorer/Californium/Here is list of live node for Californium to connect to, Pick all the ones that have inbound : true
Run your full node for few days so your system has list of all the live nodes. Not all are running every time. So it is good to have as many live node connection or sometimes live connection as possible. Off course if you run some mining operation for few days everyone would know your IP and next time as soon as you get on you can sync.
