you seem on the right chain. your hash on block 2505086 is good.
latest checkpoint is
{
"synccheckpoint" : "ec251fa0ef553ac33ed2e5de6e9b9e0b87e85d013b06f855d46ea513c313c1f0",
"height" : 2511092,
"timestamp" : "2018-04-21 19:40:57 UTC",
"policy" : "strict",
}
blockchain seems stalled because no coins are staking on the network... all my coins have not enough age, so I'll be out a couple days still.
This is the latest getcheckpoint I am getting
11:39:44

I am still mining the current chain I am on. It mentions 316 blocks remaining. I have plenty of coins to keep the blockchain moving for a bit.
