We've installed hubot on the same server as MM. Set up an outgoing webhook with trigger word and carefully configured all the env variables that hubot requires. So I type the trigger word at the beginning of a message in the specified channel but nothing happens. I see hubot listening on its port. when I monitor that port with tcpdump, I don't see anything, I would have expected to see some traffic from MM.
What can I do to troubleshoot? Are there logs for MM? Anything else? Thanks
