I set one up yesterday on Win7 64. It wouldn't sync until I added a HyperStake.conf file, although restarts seemed to help nudge it along part way.
I thought the suggested conf file was on the OP here, but I don't see it today. Perhaps it is being edited/updated or I have just forgotten where to find it.
Anyway, the conf file I found yesterday included:
addnode=192.241.233.70
addnode=104.131.135.232
I'm guessing that the addnodes were the key to syncing.
This is interesting, using the block explorer as a DNS seed should prevent any need to use a .conf. Wonder why it is acting up?
Maybe a red herring. I just did this:
1. Shut down a synced version that was using the .conf file, was on block 112150 and had 12 connections.
2. Renamed the .conf file so it wouldn't be found.
3. Restarted qt (as admin) with no .conf file.
It synced right away, and is showing block 112152 and 10 connections after spending a minute or three with one connection.
Magic.
