That is in the normal range for CHTA/NENG. The time a swap takes is set mostly by the block spacing of the two chains involved, so a pair with slow blocks is slow for everyone, every time.
The swap stopped at TakerFeeValidateFailed. The taker's fee did not validate, so the swap stopped before any payment.

Recorded by the swap's own protocol log, which is the only source that knows: the aggregator reports failed and completed swaps identically. Nothing changed hands, so it sets no reference price.
Only completed swaps are checked against a chain, because the check asks whether the agreed trade actually settled. This one did not complete, so there is nothing of that kind to confirm.
