We currently have investigator 10.6 but have been unable to use it and would like to test lua parsers with it.
From this error, I assume it's not connecting to our proxy, but I see no way to enter proxy information.
Trying to do the enterprise install, which device should be point the remote collection to? Broker over 56003?
We haven't been successful tying it to any of our devices.
I can't help with your error, sorry.
However, for testing lua parsers you'd import pcaps into it - they will be parsed by the parsers enabled in Investigator. You don't need to connect it to another device (e.g., broker). Anything pulled from another device has already been parsed by Decoder.
