We have received reports that users are experiencing issues with the FLS system invalid serial numbers (note this issue is not affecting those using the FlowJo Portal licensing system). We have found some networks experience an issue when not using a secure connection. This issue can be resolved by checking the “Use HTTPS for Authentication Requests” box that is located under the Preferences (heart icon) then “License”.

After making these changes, please restart FlowJo to ensure the changes are saved. 

If you are still experiencing issues authenticating FlowJo with your FLS site, please contact us at flowjofls@bd.com.

Thank you,  

The FlowJo Team
