Why am I getting a certificate error for ROLLER Connect? – Help Center

Effective May 26, 2026. This article details a workaround for a known issue affecting a small number of POS devices from a recent ROLLER Connect update. A permanent fix is being rolled out in an upcoming release. If you're still seeing this error, follow the steps below to resolve it and if you need assistance contact the ROLLER support team.

Introduction

A recent ROLLER Connect release was distributed with a code-signing certificate that's no longer valid. POS devices that downloaded the update, typically overnight or when the device was turned on the day of the issue, display a certificate validation error the next time ROLLER Connect tries to start. The auto-updater has since been paused to prevent more devices from picking up the affected version, and a corrected build will be published in an upcoming release.

Solution

Uninstall the affected version of ROLLER Connect on each impacted POS device, then reinstall with the version from Hardware settings in POS. The download link in POS points to a working version, so a fresh install resolves the certificate error and restores receipt and docket printing.

Reinstall ROLLER Connect on the affected POS device

On the affected POS device, close ROLLER POS.
From the Windows Start menu, search for Add or remove programs and open it.
Select ROLLER Connect (or ROLLER Connect Windows Service) in the list and select Uninstall. Follow the prompts to complete the uninstall.
Open ROLLER POS and sign in with a ROLLER administrator account.
