Any ideas ?
Me too. I was running Bitcoin ABC 0.16.1 and it got stuck on block 530361 (same on two different installations).
I've read somewhere that the network protocol changed after block 530361.
Then I downloaded the latest 17.3.0 but it still doesn't work.
However I'd need to keep 0.16.1 because - as to my knowledge - later versions don't work with Armory.
Anybody knows how to get it un-stuck from block 530361 ?
You should run command to reconsider block that was stuck. See here for details https://github.com/Bitcoin-ABC/bitcoin-abc/issues/213
I'd suggest you delete/rename the blocks and chainstate command just to see if that does anything.
I don't think it'll do much though as it looks like there is just a connection issue caused somewhere - but if you both have it maybe it will.
