    XMPP - host-unknown - fail to connect AWS Ubuntu Openfire from Windows Spark



      I setup openfire on AWS Ubuntu. And I installed Spark on Windows, and tried to login with the username/password, which were created on Openfire. However, I failed to connect the server from Spark.

      "ec2-..compute.amazonaws.com" is my AWS server's ipv4 public DNS. I can access my server through internet from Windows browser, by entering "ec2-..compute.amazonaws.com:7070".

      AWS Security Group


      Openfire setup:

      XMPP Domain Name: ec2-..compute.amazonaws.com


      usrname: test // password: pwd // email: test@ec2-..compute.amazonaws.com


      usrname: test // password: pwd // domain: ec2-..compute.amazonaws.com


      I have open port 5280 and 7070 for firework.

      What is the Error:

      However, I am still unable to connect to openfire. It shows host-unknown, saying that "This server does not serve ec2*.*.compute.amazonaws.com". Here are more details:

      Anything Missing:

      Do I need to add more ports on Windows firewall?

      Do I need to setup anything for TLS/SSL certificates on Openfire?

      Thank you !!
