It might be because the selector Hasn't rendered yet , try putting time.sleep() just before that line so that it waits for the selector to load.

The code worked one year ago. It may need tuning now, because the youtube comment page elements could be changed. However, I stopped using this Bot because Google can detect this behavior and block your account. Use it at your own risk.
