The Sync Status button in the Linnworks header allows you to see currently running sync processes, queued sync jobs, and any errors for previous processes. If there are any errors, then the sync status button will also show the number of errors on a red background. It is recommended to check these sync errors, because they may indicate that some actions may be required from the user.

Single error messages during sync

Error examples:

  • An existing connection was forcibly closed by the remote host

This error means that the server which Linnworks was connecting to has shut down the connection. It could be caused by issues with the sales channel servers or network connection between those servers and Linnworks sync servers.

  • error Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

This error messages means that the communication between the channel and Linnworks timed out due to the job taking longer than usual because of an issue on either side of the systems or just general slowness.

These are normally "one-time" errors and next syncs run successfully. Such errors do not have a detrimental effect on your account. The sync process could be delayed a bit by such errors, but it will then pick up where it stopped and there will be no further complications.

If you received 1 such error over 100 successful syncs, then there is nothing to worry about.

Many error messages in a row

Many errors in a row will delay sync and may also indicate a larger problem with the sync and may require certain actions from the user.

In the automation logs, it can look like this:

Some error examples:


  • Authorisation token is hard expired. User needs to generate a new token for this application.

If the eBay token expires and no new token is generated, Linnworks will be unable to make API calls in that user's name. This has no effect on the user's eBay account, but it doesn't allow Linnworks to interact with eBay.
