"Had failed" is in the past perfect, which is used to indicate that an action was completed before another action in the past. This option doesn't match the context of the sentence, as there's no other action in the past that this is being compared to. "Was failing" is in the past continuous, which is used to indicate that an action was in progress at a specific time in the past. But this option doesn't match the context of the sentence, as the speaker is describing the result, not the progress of the action.
