Tella saves your video to local browser storage (IndexedDB and OPFS) while it uploads to our servers. If the browser can’t write to that storage for any reason — a corrupted browser profile, an antivirus interfering with disk writes, or a profile on a failing drive — Tella will stop the recording so it doesn’t disappear into memory and get lost. This is different from running out of storage space (we have a separate article for that). Your disk has room — your browser just can’t use it.

​
Try these in order

​
1. Restart your browser

Closing and reopening the browser clears most transient issues. Quit completely (don’t just close the window — make sure no Chrome / Firefox processes are still running), then reopen and try recording again.

​
2. Clear site data for tella.tv

Sometimes the local storage for a single site gets into a bad state. Before clearing it, wait for any uploads to finish and download a copy of important recent recordings. Clearing site data permanently removes chunks that have not reached Tella’s servers yet. Chrome:
  1. Open chrome://settings/content/all in a new tab.
  2. Find tella.tv and click it.
  3. Click Delete data.
  4. Reload Tella and try again.
Firefox:
  1. Open about:preferences#privacy.
  2. Under Cookies and Site Data, click Manage Data….
  3. Search for tella.tv, select it, click Remove Selected.
  4. Reload Tella and try again.

​
3. Try a different browser profile

If clearing data doesn’t help, your browser profile may be more deeply corrupted. Create a new profile and sign back in to Tella:
  • Chrome: click your profile picture in the top right → Add → set up a new profile, then visit tella.tv and sign in.
  • The Mac app uses its own storage and isn’t affected by this issue.

​
4. Check antivirus and disk health

If the problem persists across browsers or profiles, the issue is likely below the browser:
  • Antivirus / endpoint security: some tools (Sophos, McAfee, Symantec) lock or scan browser storage files in ways that block writes. Check if your IT team has a Tella exception you can apply.
  • Disk health: a failing SSD can return errors that look identical to “storage broken”. On Mac, check Disk Utility → First Aid; on Windows, run chkdsk from an admin command prompt.

​
Still stuck?

If none of the above fixes it, message us with the date and time of the issue and the email you use with Tella. We can pull diagnostic logs to see exactly what’s happening. While you’re stuck, you can also try recording with the Tella Mac app or Chrome extension — they use different storage paths and may work even when the web app can’t. If this error came from the Chrome extension, don’t clear tella.tv site data; restart Chrome and contact support if it continues.
