I'm using https://github.com/robbiehanson/XMPPFramework to connect to my own ejabberd server, but it always failed after negotiation.

here is the log I got: 2014-01-17 07:14:40.780 Chat[48246:70b] error: (null)

Check if the solution reported here https://github.com/robbiehanson/XMPPFramework/issues/131 solves your issue.

Generally when the server is closing the connection, you get this error/ Two reasons when the server closes the connection:

1. You are not sending regular pings if the client idle.
2. You are logging in from some different client with the same credentials, and in the server settings have the setting: Always kick - If there is a resource conflict, immediately kick the other resource. in Server>server settings>resource policy.
