Vision was using an expired certificate which has been updated to use a newer certificate by the same [trusted certificate authority](https://letsencrypt.org/certificates/) as of September 30, 2021. Although this has been updated on the Tulip cloud side, some Tulip Players running on Windows machines might encounter a problem connecting to the cloud using the newer certificates. You might see a warning in your Player logs similar to: ``` Realtime API reconnection error: "Error: Failed to retrieve WebSocket URL for connection "models-xxxxx" due to REST API error with message "request to https:///api/v2/ws/connect/models failed, reason: certificate has expired" ``` This is likely caused due to the conflicting expired certificate still present in the Windows Certificate Store on your computer. ## Prerequisites * When performing this procedure you must be logged into the machine as an Administrator or have "Run as Administrator" permission enabled for your user. ## Solution Procedure In order to rectify the certificate error you can follow these steps: 1. Go to this website using any browser (Chrome preferred) on your Windows machine. This auto-prompts Windows to add the certificate (if not previously present) to the certificate store. 2. Use the Windows + R keys to open up the Run command box. Type in "mmc" to open up the Microsoft Management Console. :::(Info) (NOTE) If you are not logged in on an Administrator account you will need to run "mmc" as Administrator (this can be achieved by holding Shift+Ctrl when clicking "OK" in the Run dialog). ::: ![](https://cdn.document360.io/7c6ff534-cad3-4fc8-9583-912c4016362f/Images/Documentation/Fixing%20%27Realtime%20API%20reconnection%20error%20-%20certificate%20has%20expired%27%20for%20Vision_397189546.png) 3.
