| Error | What it means | What you can do about it |
|---|---|---|
| Sync.SyncScheduler DEBUG Got backoff notification: 3600000ms | The server is currently underwater and is asking the sync client to try again later. | All we can do is wait until the server no longet has a heavy queue. Please notify the team if this goes on for more than 24 hours. |
| Sync.BrowserIDManager ERROR Failed to fetch a token for authentication: TokenServerClientError({"message":"assertion argument is not valid."}) OR Sync.Status DEBUG Status.login: error.login.reason.network => error.login.reason.network | There was a login failure and an underlying server or network error. | TBA |
| Error in UI | What it means | What you can do about it | |
|---|---|---|---|
| "Unexpected error" on sign in | The server encountered an error when trying to log you in | Report this to the sync services team and file a bug with the affected platform above. | |
| Exceeded limit or link is expired on Password reset | You have tried to reset your password 10 times | All we can do is wait 30 minutes to try the reset again. Please also check the spam filter if you have not received an email. | |
| Sync.Status DEBUG Status.login: success.login => error.login.reason.no_recoverykey OR Wrong Recovery Key | IF you are on the old sync, please update to the new one. If this occurs on the new sync there may be an expired token. | Remove the account and add the account back. | |
| Sync options are greyed out. | This means the sync is in progress or the error message on the page. | On android, enable sync data for the Firefox Account. On the Desktop this should not happen. | |
| "Unknown Account" | This means that your account is not recognized. | Could you have set up your account on the old sync? Please update to the new one. | |
| "Sync encountered an error while syncing: Incorrect account name or password. Sync will automatically retry this action" and a "Preferences" button." | This means there is an issue with the login | Check the saved login it it is, and if it continues to happen check if cookies are saved in the browser settings. |
