Some of my recent transactions are not confirmed and if I try to use a tool such as this or this, I get an error saying "Inconsistent subtangle" or "Cannot find tail" or "Inconsistent tips pair selected". What do these mean and how can I avoid them?


"Inconsistent subtangle" - transaction you want to promote is referencing an invalid transaction (or one that was confirmed in other reattachment). That means you have to use reattach.

"Cannot find tail" - not sure, maybe this node doesn't see this transaction or it isn't a tail (transaction with index 0 in the bundle)

"Inconsistent tips pair selected" - it's an error from the node when it can't find consistent tips. You can just try again.

    Thanks for explaining this. It's worth mentioning that "Inconsistent subtangle" and "Inconsistent tips pair selected" was not resolved by reattaching multiple times. – user1654 Feb 13 '18 at 17:25
