@BAS-Viet-Nam Okay, thank you for the hint. Worked on many sites with these 2 functions without any problems. So I will try it with "Wait while element exists" on this specific site.
Hopefully I don't get in an endless waiting-loop ;)
yes, I hope that you are entering the ip of the proxy, and not your computer. Check which ip you have allowed for these proxies and whether it corresponds to the ip of the computer on which you are running the BAS. Also check if this proxy works in a normal browser.
Seems to be a bug, if you have tunneling enabled it leaks your ip and if you disable tunneling you can't continue to click to next page on some urls, seems to be a bug.
