"use each line one time" along with "Only read" setting.
That way each thread will start new browser instance and
use new resource line because its set to use each line only
one time. When all proxies are used one time, script will
finish.
I get this output on proxies that are working in other applications.

i tested pages google .com and tumblr. com
Whats wrong? I loaded proxies from resource, that loaded proxies from text file one proxy:port per line.
Edit
For example 31.182.52.156:3129 works on firefox when checking google com:

I have no clue what I do wrong! I followed tutorial
@yourfriendkarol I checked your proxy, everything works fine.


Thanks buddy! Although I get this error very often, its less of a problem now because I've created "Proxy Checker" that literally tests decimals of proxies in less than a minute.
However I still wonder why i get this error (what happens quite often), while proxies work for me in other software/browser.
I have exact settings as you have.
I have the same problem:
Proxys from VIP72 working in real Browsers, but in BAS i get error:
"Timeout during LoadPage https://whoer.net" 95%
How to fix it or how to limit concurrent connections per proxy?
