Problem
Ethernet link renegotiation briefly disconnects the encoder and terminates the live broadcast.
Solution
Root Cause / Diagnostic:
Damaged Ethernet cables, faulty RJ45 connectors, or aggressive Energy-Efficient Ethernet (EEE) power-saving features cause the network interface card (NIC) to renegotiate link speeds mid-broadcast. During auto-negotiation, the network interface temporarily drops carrier signal for several seconds. This socket reset terminates the active RTMP session, causing YouTube to abruptly conclude the live stream.
Actionable Fix:
1. Disable 'Energy Efficient Ethernet', 'Green Ethernet', and power-saving sleep modes in Windows Device Manager NIC properties.
2. Hardcode NIC link speed to full duplex (e.g., 1.0 Gbps Full Duplex) rather than auto-negotiate, and replace suspect patch cords with certified Cat6 cables.
3. Test physical interface stability under heavy bidirectional throughput using iPerf3 to confirm zero link flaps or carrier state resets.
Pro Tip:
Disable 'Auto-stop' in YouTube Live Control Room settings; this keeps your stream room open with a standby slate if an unexpected physical reconnection occurs, preserving your live audience.
