Org.jivesoftware.openfire.net. SocketReader - Closing session due to incorrect hostname in stream header

This morning my OpenFire client is started to turn on and off I went to check the log and this shows me.

The strange is that only clean the system caches and reconnect.

Thank you for your help.
