I just wonder if it's something in the 3.0.0 or the 3.0.1 client or both. I suck at crypto, is there something I could put in my conf to block node2.bullion.one? So I can test it and see if it's that? I dunno, I'm currently reindexing right now.
As far as I know, there is no explicit way to manually block a node. However you can force the wallet to connect only to some predefined nodes, and reject all others.
For that you need to remove "addnode=" entries from your bullion.conf (in case if there were any), and add "connect=" nodes pointing to the hosts you want to exclusively connect to.
So, basically, you need to put this into your bullion.conf:
connect=95.217.77.209
connect=82.21.164.47
connect=89.210.233.40
connect=24.55.154.69
connect=73.121.220.52
However I doubt this will actually help... Worth a try, anyway. I already did so.
