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.
@fox i removed "parse line" action that is immediately after project start AND the crash changed to missing variable error. will look more into it. basically i used a keyword that had no value, or its only value was a word assigned by "parse line" before, that was a temporary value anyway.
