only grey (21 ones), no white!
Height is 46562
I use v2.2.1.2210 (new compiled)
In the log I only see blocks with too weak PoW, some "failed to Invoke_Command_Handshake" and Infos about starting to synchronizate
Is this definitely running off the new 2.2.1 daemon?
The command above is for sync errors between nodes; grey peers do not sync.
Have you downloaded the .tar.gz snapshot of the blockchain to put in to the node as well?
This helped for myself.
