Browsersim is refusing to open pages on localhost - but will open the pages on 127.0.0.1 ---------------------------------------------------------------------------------------- Key: JBIDE-18713 URL: https://issues.jboss.org/browse/JBIDE-18713 Project: Tools (JBoss Tools) Issue Type: Bug Components: browsersim Affects Versions: 4.2.0.Final Environment: RHEL6 Oracle JDK 1.7 Reporter: Len DiMaggio Priority: Critical Attachments: Screenshot-127-0-0-1.png, Screenshot-localhost.png, ticket-monster.war See the attached screenshots - I am seeing a consistent pattern where browsersim cannot open a URL that specifies localhost, such as: http://localhost:8080/ticket-monster/mobile.html But it is able to open a URL for the same page, if it specifies 127.0.0.1, such as: http://127.0.0.1:8080/ticket-monster/mobile.html See the attached screenshots.
