When Vuze is not seeding (uploading files to others) or connecting to seeds (downloading from others), the issue usually stems from network configuration, client settings, or the health of the torrent swarm itself. 1. Network and Connectivity Issues

To be "connectable" in the BitTorrent world, your router must be configured to forward the specific port Vuze uses. You can test your port on sites like CanYouSeeMe.org . If the port is closed, other peers cannot initiate a connection with you.

Windows Firewall or third-party security software like Avast can block Vuze's traffic. Ensure Vuze is whitelisted in your Windows Firewall settings.

If encryption is set to "Required," you can only connect to peers using encryption. Setting it to "Enabled" or "Prefer Encryption" allows a wider range of connections.

Specific settings within the Vuze client may prevent seeding even when the network is clear.
