Failed to establish listener for incoming data

From VuzeWiki

[edit] Failed to Establish Listener error messages

It means Vuze cannot open up its TCP listening port (by default 6881) because it is being blocked. This is usually due to software firewalls, like Norton, ZoneAlarm or Windows firewall, but can also be caused by other installed network utilities, which block/change socket level access.

Your best bet is to disable or UNINSTALL any existing firewall software completely, and then reboot, before running Vuze. If that solves things, a re-install or update of the culprit application can help. Please note that running without a firewall can be dangerous, so the advice is merely for helping in identifying the problematic software.

Another reason might be that some other application happens to already use just that port. You might try another port. Read also Port_is_blacklisted.
