If OBS says your YouTube stream key is rejected, first copy the current key from YouTube Studio’s Live Control Room and update OBS. Then verify that the server URL and protocol are correct. A rejected-key message can be a credential mismatch; a timeout, SSL error, or “failed to connect to server” points instead toward the server/protocol setup or the network path. YouTube and OBS publish general troubleshooting steps, but those instructions do not establish that JioFiber specifically blocks YouTube Live.
1. Replace the saved key with the current YouTube key
-
In YouTube Studio, open Live Control Room and select the stream you intend to start.
-
Copy the current stream key and paste it into OBS’s stream-key field. YouTube’s troubleshooting guidance for a third-party encoder error is: “To fix it, get a new stream key in the Live Control Room and update your encoder.” YouTube Help: Troubleshoot live stream errors
-
If you reset the key, replace the old saved key in OBS; changing it in YouTube alone does not update OBS. YouTube says only a channel owner or manager can reset a stream key. YouTube Help: Manage your live stream settings

SaleTP-Link AX1800 WiFi 6 Router (Archer AX21 V5)- DUAL-BAND WIFI 6 ROUTER: Wi-Fi 6(802.11ax) technology achieves faster speeds, greater capacity and reduced network congestion compared to the previous gen.

- CONNECT MORE DEVICES: Wi-Fi 6 technology communicates more data to more devices simultaneously using revolutionary OFDMA technology
- EXTENSIVE COVERAGE: Achieve the strong, reliable WiFi coverage with Archer AX1800 as it focuses signal strength to your devices far away using Beamforming technology, 4 high-gain antennas and an advanced front-end module (FEM) chipset
- OUR CYBERSECURITY COMMITMENT: TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Secure-by-Design pledge. This device is designed, built, and maintained, with advanced security as a core requirement.
Check for an accidental leading or trailing space when pasting. If you use saved settings for a previously created OBS stream, do not assume they contain the current key—inspect the field.
2. Verify the server URL and key are in the right OBS fields
The server URL and stream key are separate values. The server belongs in OBS’s server field; the key belongs in the stream-key field. Compare both against the setup for the selected YouTube stream rather than pasting one value into the other field. YouTube’s encoder setup instructions distinguish the server URL from the stream key: Set up your encoder for live streaming.
If you connect by signing in to your YouTube account inside third-party software instead of entering a key, YouTube advises contacting that software’s support team; the integration may need updating. YouTube Help: Troubleshoot live stream errors

- Advanced Security with WPA3 - The latest Wi-Fi security protocol, WPA3, brings new capabilities to improve cybersecurity in personal networks
3. Match the protocol to the server URL
If OBS reports an SSL error or timeout, changing the key repeatedly is unlikely to address the immediate issue. Check that the selected protocol and server URL agree. For RTMPS, use the RTMPS server URL, and confirm that the encoder supports RTMPS. YouTube says port 443 can be specified when troubleshooting an SSL error. Follow YouTube’s current encoder instructions for the exact server value and format rather than guessing or substituting a URL. YouTube Help: Stream using RTMPS
Crashes, No Sound, or Screen Glitches?

Once the key, server, and protocol are correct, treat “failed to connect to server” or a continuing timeout as a connection problem to diagnose—not proof that the key is invalid or that JioFiber is at fault. Change one condition at a time so the result is informative.
Update OBS and test Ethernet
-
Install the current OBS version, then retry the same stream settings.

-
If the computer is on Wi-Fi, connect it to the router with Ethernet and test again. If that works, it points toward Wi-Fi or local-network conditions; it does not prove the key was valid or establish a JioFiber fault. A standard Ethernet cable may be useful for this conditional test, but it will not fix a stale key or an incorrect server URL.
Check VPN, security software, and OBS network settings
-
Temporarily test without a VPN, if one is active. Check whether firewall or security software is interfering with OBS’s outbound connection; avoid leaving protections disabled after testing.

Restart the router and compare another connection if available
-
Restart the router/modem if general connectivity is also unstable, then retry.
-
If you can safely test a temporary alternate internet connection, use the same OBS configuration. A successful test on another connection makes the original connection path a variable worth investigating; it does not, by itself, identify which part of that path is responsible.
These steps follow OBS’s general connection troubleshooting guidance, which lists unstable connections, Wi-Fi, VPN or security software, IP-family selection, router/modem conditions, and ISP-side issues among factors to investigate. It does not identify a JioFiber-specific YouTube Live block. OBS Project: Stream Connection Troubleshooting

5. When to contact Jio support
Contact Jio support after confirming the current YouTube key, the separate server and key fields, the selected protocol, and OBS’s basic network conditions. Explain what you tested and when the connection fails. If wired Ethernet or an alternate connection changes the result, include that comparison; it helps narrow the issue to a connection path without proving a specific JioFiber restriction. Do not assume a port-forwarding change is needed: the cited OBS guidance focuses on diagnosing connection conditions and contacting the ISP when necessary, not opening inbound ports as a default fix.
