Short answer: A public-IP change alone is not established as a reason YouTube ends a live stream. The interruption that often accompanies it—a dropped WAN or internet session—can break the encoder’s connection. Keep your existing stream URL and key, check which link failed, enable and test your encoder’s reconnect behavior, and confirm the result with an unlisted test before relying on it.
Does changing your public IP require a new YouTube stream key?
Usually, do not reset the key just because the ISP-assigned public IP changed. YouTube’s encoder setup uses a stream URL and stream key; YouTube describes the key as the encoder’s password for sending the feed. Its published instructions do not say that a key is tied to the creator’s public IP or must be replaced after an IP change. See YouTube’s stream settings guidance and encoder setup instructions.
A key change is a separate troubleshooting step. YouTube mentions generating a new stream key for certain encoder start errors, not as a general response to an ISP address change. First check the encoder’s own status, the router or ONT’s WAN event log if available, and the event’s stream health in YouTube Live Control Room. YouTube’s live-stream troubleshooting guidance recommends checking the encoder and outbound connection.
Set up reconnect and identify what actually failed
Before the next stream
- Keep the event settings available. Confirm that the encoder has the correct YouTube server or stream URL and the existing key. Do not create or rotate a key solely because the public IP changed.
- Find your encoder’s reconnect setting. Turn on its retry or reconnect behavior if available, and check the current official manual for the exact label and what happens after a WAN interruption. The YouTube pages cited here do not specify OBS or another encoder’s control names, retry timing, or whether it can rejoin the same event after a reset, so those details depend on the encoder and version.
- Check the connection path. When the problem occurs, note whether the router or ONT lost WAN service, whether the encoder reports a dropped connection, and whether YouTube Live Control Room reports incoming video or a stream-health problem. Compare the timestamps rather than assuming the IP change caused the outage.
- Check outbound upload capacity. Use a direct connection test and confirm the connection recovers. YouTube advises allowing upload headroom rather than setting the stream bitrate to the maximum speed-test result; shared connections can reduce the bandwidth available to the encoder. Follow the current YouTube encoder settings and bitrate recommendations for your codec, resolution, and frame rate. They can change, so check them before setting up a new stream.
- Use RTMPS where your encoder supports it. YouTube’s current encoder guidance recommends RTMPS for encrypted ingestion. Use the server URL and key shown in your YouTube setup flow, and verify the encoder is configured for the matching destination.
- Test the full recovery path. Run an unlisted test, check the YouTube preview and stream health, then deliberately interrupt the primary connection and observe whether the encoder retries and what viewers see. YouTube advises testing the encoder and preview and checking failover behavior; its live-stream tips describe testing by stopping the primary encoder or disconnecting its Ethernet cable.
During an interruption
- Record the time the encoder lost connection and the time it recovered.
- Check the router or ONT WAN log, if it provides one, for a link drop, PPPoE session reset, or DHCP renewal around the same time.
- Check YouTube Live Control Room to see whether it stopped receiving the feed, reports stream-health trouble, or still shows an incoming connection.
- Once internet access returns, let the encoder’s configured retry behavior act; if it does not reconnect, follow that encoder’s documented procedure and check the YouTube event state before restarting or creating another event.
A visible gap is possible: the available YouTube guidance does not promise that a broadcast will resume without interruption after a network reset. Do not assume that an encoder retry preserves uninterrupted playback or rejoins the same event in every setup.

Is the IP change the cause, or did the WAN session drop?
An address reassignment can coincide with a router reconnect or authenticated-session reset, but the address change by itself is not confirmed here as the cause. YouTube identifies connection reliability, upload bandwidth, encoder health, and outbound connectivity as troubleshooting factors. Its guidance says to contact the ISP if connection tests indicate a problem.
If the public address changed but the encoder remained connected and YouTube continued receiving a healthy feed, that points away from a simple IP-change explanation. If router WAN logs, encoder errors, and YouTube stream-health timestamps line up, a connectivity interruption is more plausible. The reader’s ISP, router, encoder, and event logs determine the diagnosis; verify with the ISP and the encoder’s documentation rather than treating correlation as proof.

What to ask your Indian ISP
Contact the provider with the incident time and ask specific questions about the connection on your plan:
- Did the router’s WAN, PPPoE, or DHCP session drop or renew at that time?
- Is the connection assigned a dynamic public IP, or is it behind provider-side NAT?
- Is a public or static IP option available on this exact plan, and what are its current terms?
There is no universal Indian ISP policy established here for public-IP assignment, CGNAT, or static-IP availability. A TRAI-hosted consultation response by Derick Thomas dated 20 January 2016 argued that customers needing a public IP should receive one without charge. That is a historical respondent’s position, not a binding current TRAI rule and not evidence that a particular provider offers a public or static IP on your plan.

Reduce connection risk and plan a backup
Stabilize the primary connection
If your encoder computer supports it, Ethernet can reduce variability caused by Wi-Fi. It does not prevent an ISP from resetting the WAN session or changing your public IP. YouTube’s general advice is to prioritize a reliable connection, allow adequate upload bandwidth, and test under the conditions in which you will stream.
Decide whether a second internet path is worth it
A genuinely independent backup connection may help if a long interruption would be costly, but it adds setup and recurring cost. Compare whether the backup uses a separate access network or provider, its real upload performance, the interruption during failover, and whether your encoder supports the arrangement. YouTube’s advice to test a backup encoder is not proof that a second ISP path will switch seamlessly. No specific dual-WAN device or Indian broadband plan is established here.
