You proxies probably got blocked from harvest 1 to harvest 2, either just because they are public and die crazy fast or while doing harvest 1. The only thing needing fixed is you need new proxies.
If you notice in the harvest run that had less results it had way more errors, that is blocked ips.
Your problem = proxies. Nothing Scrapebox can do to fix your proxies.
You see duration? It's not a proxy problem...
