I have been having problems with proxies for the last 3 or 4 days. BAS sometimes activates proxy. sometimes it doesn't activate. I have been using the script for 1 month, there was no problem before. There is a problem for the last 3 or 4 days.
Not that I know of. You'll need to tunnel through the proxy to really check the connection. I either do a proxy checker site to make sure nothing is leaking, or I just do the simple GET request against the site(s) I'm working with/on.
