I have near about 25 computers in network all are running Windows Xp. In all these computers, I have installed Spark 2.5.8 as Jabber client. I have installed OpenFire 3.6.4 as Jabber server on centos 5.2. In all computers, everything works perfactly. But I cannot understand why I cannot login through Spark from one computer.
I can login through all other computers using same login details. But from one computer, I get an error “Invalid username or password”. I have tried to use other Jabber clients like Pandion. They all works correctly. Only Spark does not work!
I do not understand why it happens. Can anyone suggest what should be the solution for this?
