Wallet blockchain update issue "No block source available..."
I just updated to the latest wallet v0.12.1.6 (64bit Win)
I show 6 active connections to the network
Still 41 hours behind with "No block source available..."

What is the fix?


Update:  I had to kick off all connections to agents running core:0.12.1.5   Then the synchronization began.  
Problem solved.
