What i meant by failure is that you should start anew. It can be the same story, entirely revised, but at least you get the chance to be in new rankings and have some visibility again. Even better, if you change the title and the cover.
Especially, if your valid views have dropped on a day to day basis and the average number of chapters read keep lowering as well. If it's like this for months, it means your retention rate has become bad. The issue is that even if you revise your problematics chapters, the old readers that stopped reading you won't miraculously give a new read to your story. In their head, your story has already been labelled. The oldest your story, the highest will be the number of readers you definitely lost.
That's what i would do. I take all the advices, i keep what is good and remove what is bad, then start anew.
Of course, if you're contracted or aiming for paper edition, then finish your novel and take your time. It is another situation.
