I sent some transactions to the IOTA Tangle. However, according to thetangle.org website, they are not confirmed yet. You can see one of them here :
As you can see in this transaction information, I promoted it several times. Also, I reattached and replayed it, but no result.
Is there a solution for this problem? And is it possible a transaction never get confirmed? If so, it seems to be a significant issue in IOTA, isn't it?
