listen server socket does not appear to be accepting inbound connections

[drpaneas 1]

I am using Vuze with a private tracker and I get this warning:

 

listen server socket  on [iP:Port] does not appear to be accepting inbound connections {operation timed out]

 

Is this normal? What does it mean?
