If PRISM Live Studio says your YouTube login has expired, reconnect the linked YouTube account in PRISM. If you configured YouTube with Custom RTMP, copy the current stream key and server URL from YouTube Studio and update them in PRISM instead. These are different connection methods, so first identify which one you use.
Identify how PRISM connects to YouTube
| Connection method | What PRISM uses | What to update |
|---|---|---|
| Linked YouTube account | Your YouTube account authentication, which lets PRISM access YouTube features | Sign in again or remove and relink the YouTube account in PRISM |
| Custom RTMP | A manually entered YouTube server URL and stream key | Copy the current URL and key from YouTube Studio into PRISM |
PRISM’s mobile guidance for a “YouTube login has expired” message describes an expired login session, not necessarily an expired RTMP key. The wording alone does not establish which connection failed. Check whether you linked your account or entered RTMP details before changing credentials. PRISM’s expired-login guidance · PRISM FAQ
Reconnect a linked YouTube account
- End an active broadcast before reconnecting. PRISM says an expiration notice during an active broadcast does not affect that stream; reconnect after the stream ends.
- Open PRISM’s account connections. Depending on the app version and device, disconnect YouTube and add it again under My Channel, or open Settings > Live Service Accounts and relink the platform.
- Sign in to the correct YouTube account and complete the authorization prompts.
- Retry the broadcast. In YouTube Live Control Room, confirm that PRISM’s encoder feed appears as a preview. For a scheduled broadcast, wait for the preview and then select Go live in Live Control Room.
PRISM’s mobile expired-login guide says to log in again, while its FAQ documents general reconnect paths. The exact labels may differ by app version and device; the mobile guide does not document a current desktop menu path for this particular error. PRISM mobile guide · PRISM FAQ · YouTube encoder instructions
Update a Custom RTMP key in PRISM
- Open YouTube Studio and go to Create > Go Live > Stream.
- Copy the current stream key and server URL. YouTube says only a channel owner or manager can reset a stream key. If someone reset it, the encoder must be updated with the new key.
- Open PRISM’s Custom RTMP settings and replace the saved server URL and key with the current YouTube values. Check for missing characters or extra spaces.
- Start the stream from PRISM and check Live Control Room for the encoder preview. For a scheduled broadcast, select Go live after the preview appears.
Custom RTMP is separate from linking a YouTube account. PRISM’s FAQ notes that this method does not show in-app viewer counts or chat. YouTube: Manage live stream settings · PRISM FAQ · YouTube encoder instructions

When using an adapter, if the device is recognized as USB 2.0, try using the other side with the USB-C port. Simply flip the capture card and reconnect it to be recognized as USB 3.0
If reconnecting or replacing the key does not work
- Check the connection type again. Relinking an account will not repair a stale RTMP key, and replacing an RTMP key will not renew an expired linked-account login.
- Verify the server URL and protocol. PRISM flags an incorrect or outdated server URL and an unsupported protocol as possible causes of stream-key or channel-access errors. Use the current YouTube stream details and a supported connection method.
- Confirm YouTube live-streaming eligibility. YouTube says a channel must be verified and must not have had live-streaming restrictions in the past 90 days. Check the channel’s status if YouTube does not accept the connection.
- Look for the encoder preview in Live Control Room. If the preview does not appear, the stream has not reached the point where you should select Go live; recheck the account authorization or RTMP details and try again.
