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.

Run Process runs the code as a batch file. No need to open CMD and if any program needs the cmd window (node.js server for example) it will open it as such once the desired line is executed.
When a batch file is run, the shell program (cmd.exe) reads the file and executes its commands, normally line-by-line.
@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.
