Just spent a number of days troubleshooting a Crossbar app that was handed off by another dev team.\r\n\r\nCrossbar would startup fine but when clients would try to connect to it they would just hang and never fully initiate the connection. Both the clients (nodejs and browser) and the server would not log any meaningful information despite flipping all the debug flags to True and setting AUTOBAHN_DEBUG to true.\r\n\r\nTurns out the version of Crossbar being used 0.11.1 was not locked to a specific version of Twisted and it kept pulling down the latest version (16.3.0). Locking Twisted to anything below that version resolved the issue immediately.\r\n\r\nHere is a section of the requirements file:\r\n```\r\nautobahn==0.10.9\r\ncrossbar==0.11.1\r\nTwisted==16.2.0\r\n```\r\nHope that saves others some valuable time."}}
