This issue is due to only SSL connections are allowed in Twitter API endpoints. Therefore a SSL connection is required to be initialized from TIBCO ActiveMatrix BusinessWorks Plug-in for Twitter.

To resolve this issue, Add the property "java.property.twitter4j.http.useSSL=true" in the designer.tra file to change the communication from HTTP to HTTPS.
