Sonos Error 1004 — What It Means & How to Fix It

What Does This Error Mean?

Error 1004 means Sonos could not authenticate your account credentials. This is usually caused by an expired session, a recent password change, or a temporary issue with Sonos account servers. Signing out and back in to the Sonos app almost always resolves it immediately.

Affected Models

Sonos Era 100
Sonos Era 300
Sonos One SL
Sonos Move 2
Sonos Beam (Gen 2)

Common Causes

Sonos account session token has expired after an extended period without signing in
Account password was recently changed on another device, invalidating the current session
Sonos account server is experiencing a temporary authentication outage
Two-factor authentication challenge was not completed within the required time window
App cache has stored corrupted login credentials that are being rejected by the server

How to Fix It

In the Sonos app, go to Settings > Services & Voice > Sonos Account > Sign Out.

Signing out clears the expired or corrupted session token stored on your device.
Sign back in with your Sonos email address and current password.

If you recently changed your password on the Sonos website or another device, use the new password here.
If sign-in fails again, go to account.sonos.com on a browser and request a password reset.

A fresh password reset guarantees the credentials you enter in the app match what the Sonos servers expect.
Clear the Sonos app cache on your phone — on Android go to Settings > Apps > Sonos > Clear Cache; on iOS, delete and reinstall the app.

Cached but corrupted credentials can persist through a simple sign-out and continue causing Error 1004 until the cache is cleared.
Check status.sonos.com for any active account service incidents.

If Sonos is experiencing an authentication outage, all sign-in attempts will fail regardless of correct credentials — just wait it out.
If the error persists across multiple devices, contact Sonos Support to check whether your account has been flagged or suspended.

Unusual activity on a Sonos account can trigger an account lock — support can resolve this after verifying your identity.

When to Call a Professional

Sonos Error 1004 is an account-level issue, not a hardware fault — no technician is needed. If you cannot sign in after resetting your password, contact Sonos account support at support.sonos.com. Make sure you are using the correct email address — Sonos accounts are tied to the exact email used at registration.

Frequently Asked Questions

Will Error 1004 delete my Sonos playlists or settings?

No — your playlists, rooms, and system settings are stored in your Sonos account in the cloud. Signing out and back in simply refreshes your session; no data is deleted. All settings and playlists will be exactly as you left them after you sign back in.

Can I still use Sonos speakers while Error 1004 is showing?

Yes — your speakers will continue to function using AirPlay, local audio, and TV audio inputs. Music services that require account authentication (Spotify, Apple Music) will not stream until you sign back in. Speakers already grouped or playing can often continue without interruption during an account error.

Why does Sonos keep asking me to sign in again?

Sonos account sessions expire periodically as a security measure. Being signed out of the app unexpectedly can also happen after a Sonos app update or an OS update on your phone. Enabling biometric sign-in on the Sonos app (if available) makes re-authentication faster and more convenient.
