Capture Session Failed or Stalled

What to check when the Clipus extension stops mid-capture or fails to start a session.

If your capture session fails or stalls, the cause is almost always one of three things: extension not signed in, the page blocks scripting, or your network dropped during upload.

If the extension shows "Not signed in"

Open the extension popup, click Sign in, and use the same email as your clipus.io account. The session token is stored locally and persists across browser restarts.

If the page blocks the extension

Some product pages set strict Content-Security-Policy headers that block our content script. The extension surfaces a yellow banner when this happens. Workaround: use the URL paste flow on the dashboard instead — the server-side fetch path bypasses page-level CSP.

If the upload stalls

Captures upload over TLS as you go. A network drop pauses the queue but does not lose data. Reconnect, and the extension retries automatically. If progress is stuck for over 5 minutes:

  1. Open chrome://extensions/ and click Errors under Clipus
  2. Copy the most recent error message
  3. Send it from /support/contact with the captured URL

If nothing works

Reinstall the extension. Capture sessions in progress are lost (data not yet uploaded), but published videos and saved screens are not affected.
