Scrapebox Google Proxies check > 302 IP Blocked

When using scrapebox with the new proxy manager i check for clean proxies for Google harvesting

However when i try to do manual harvesting i get error 302 (ip blocked) with all the proxies the proxy manager before few seconds marked as OK

How do you solve this issue (except from taking fresh private proxies) ?

With "manual harvesting" i mean the default non multi-threaded harvesting

How at the same moment the proxy manager reports the proxy at Google check as "passed" and the next second Google displays IP Ban error for nearly 95% of the proxies of the list ?

Apart from this i think it's essential to include a procedure where you will define the times where scrapebox will auto-disable non responsive proxies so that only the operational will participate at the query
If this doesn't happen the timeout retries will reach the number you set and you'll get no results (as it is now)

Even the private proxies is not a solution because with 10 IPs for example you will soon burn all of them when you query Google too often.
