Why Scrapebox comments failed to post?

Hello guys it is me again, why could be the reason for Scrapebox to fail posting bulk comments?
I added my keywords, I added my free online IP's, I harvesting it, , I got over 10 K URL, I filled all the loading files, Now everything failed.

Please help

probably a ip issue. try paid proxies.

I think I just replied to your other thread and someone else did too.

Use paid proxies for posting, even if its only 1 private or shared private proxy.

Then if its failing, look at the platforms box, does it mostly say the name of a platform, unkonwn or is it just mostly empty white boxes?
