License expired in prod, but works in dev

Hi, We recently upgraded our product, the app was working fine using SAML, till the upgrade . The product key that we have is valid till middle of next year. After the upgrade in the production environment, getting an error "license key expired" and failing to SSO. Can someone please help? The license key that is failing in prod is working fine in dev.

If you update your DLL to the latest nuget's package version and your subscription was expired, you may get that issue. You can use the older version or upgrade to the latest version to solve the issue.
