Handling Stream Key or Channel Access Issue

Could not access the specified channel or stream key, please double-check your stream key. If it is correct, there may be a problem connecting to the server.

The error you experienced corresponds to the OBS_OUTPUT_INVALID_STREAM error case in OBS. And it means that your stream settings are invalid or not compatible with the streaming platform you're trying to connect to.

This guide will help you understand the possible causes and how to fix them step by step.

1. Invalid Server URL

The server address you're trying to stream to might be incorrect, outdated, or no longer supported.

Try the following steps:

• Double-check the RTMP or RTMPS URL from your streaming platform (e.g., YouTube, Twitch, Facebook).

• Make sure you’ve copied and pasted the full server URL correctly into PRISM.

• Example (YouTube): rtmp://a.rtmp.youtube.com/live2

2. Incorrect Stream Key

The stream key is a unique code that links PRISM to your specific live stream. If it’s wrong, the stream won’t connect.

Try the following steps:

• Go to your streaming platform and find the current stream key.

• Copy the exact stream key and paste it into the PRISM stream settings.

• Be careful not to include any extra spaces before or after the key.

3. Codec or Resolution Issues

Your video settings might not match what your streaming platform supports.

Try the following steps:

• Try using common settings like:

  • Video codec: H.264 (AVC)

  • Audio codec: AAC

  • Resolution: 1920x1080 or 1280x720

  • Bitrate: 2500–6000 kbps, depending on platform recommendations.

• Check the platform’s documentation for the exact requirements.

4. Unsupported Streaming Protocol

Some platforms support only certain protocols (e.g., RTMP or RTMPS).

Try the following steps:

• Check whether your platform supports RTMP or requires RTMPS (secure RTMP).

• Update the protocol in PRISM accordingly.

• Example: Facebook Live requires RTMPS, not plain RTMP.

Restart PRISM after making changes to ensure new settings are applied. If you're using a custom RTMP server, make sure it’s online and reachable from your network. Some platforms require enabling streaming permissions — check your account settings.
