CSCun25517 - Feature Key Grace Period is not effective

[SlowCold]

The ESA appliance returns the following error to any new connection attempts and then closes the connection: 421 Host is not accepting connections temporarily.

How can I do to solve this issue ?

Thanks in advance for your support

By the bug if your license is expired the workaround is to upgrade to 8.5.0 and upload a non expired license file.

Thank you for your feedback. I use the version 16.0.1
The license is not expired. However, I reapplied the license and that fixed the problem.
