error in backup certifcation

[mehdibenayed]

I made a backup of the Qlik Sense certificate for the purpose of upgrading, but unfortunately, I made a mistake while following the backup and restoration tutorial. As a result, I accidentally duplicated the certificate on top of itself. Since then, Qlik Sense is not functioning properly. I attempted to resolve the issue by deleting the certificate from both "Current User" and "Local Computer" and then restoring it using "bootstrap -restorehostname," but the problem persists. Is there any solution you could propose? Thank you.

Hey,

Please refer to this other post here about a similar case.

 You may also want to try restoring the certificates on the central node of your Qlik Sense site by following the steps outlined in the Qlik Sense for administrators Help
