Yes, happened to me, got this message for a ~5 days old transaction.

The txid is still visible on mempool.space

Maybe the fee was too low (18sats/vB) and it has been pruned in the ViaBTC mempool, idk.

Later I created another txid with the same fee, it has been accepted by the accelerator but in the end has not been processed. This second txid was never been visible on mempool.space, if I try to rebroadcast, it says that the RBF fee is too low.
