Hi I am trying to send alerts to slack on NiFi using putslcak processor. I have followed put_twitter_msg_ to_ slack <https://community.hortonworks.com/articles/45531/using-apache-nifi-070s-new-putslack-processor.html> . I can able to post message to slack using curl from NiFi server, but I am getting java connection timeout error while using putslack processor. Please find detailed error . <http://apache-nifi-developer-list.39713.n7.nabble.com/file/t864/nifi_slack.png>
