This comes to no surprise to me. The first shutdown right in the active period has destroyed a lot of trust within the community that would always haunt any attempts to revive. And the first shutdown had been so long that a lot of the past members had already moved to alternatives before you reopened it. You've practically started not from zero but from -100 and Minecraft is a very unforgiving server market, much harder than SA-MP.
There is nobody to blame really, it just didn't go well for this server. Shit happens, right?
