I am using Smack 4.0.3 with my Java Spring Web MVC web application.
When I send a chat message to a Buddy, the message is sent without any delay, as is seen instantly on the Smack debugger (enabled SmackConfiguration.DEBUG). But, the message is received after a delay of approximately 1 minute.
I installed Wireshark on the same machine on which my project is running and the packet is received late on Wireshark also. This is causing a trouble creating an instant xmpp chat application. Your suggestions will really be helpful!
