Forward your port in your router for better connectivity:
session.set_listen_port(6881)
# Then configure port forwarding: External 6881 -> Internal 6881
# Option 1: Set custom bootstrap nodes (recommended for performance)
session.set_dht_bootstrap_nodes([
"router.bittorrent.com:6881",
"dht.transmissionbt.com:6881",
"router.utorrent.com:6881",

])
session.start_dht()
# Option 2: Use defaults and add more nodes
session.start_dht()
session.add_dht_node("additional.node.com", 6881)
Performance Tip: Setting a well-distributed list of bootstrap nodes can improve DHT connectivity speed.
