I have configured my FTD 6.2.3 through FDM with base, threat and malware license and all the policies are working fine. But today when i open the FDM it says license are out of compliance what causing the issue.???
One or more managed devices is using a license that is out of compliance, or the Firepower Management Center has not communicated with the Cisco licensing authority in more than 90 days.
First check the reachability of FMC with cisco Smart licensing server
System > License > Smart License and click re-authorise
License count in cisco smart licensing portal is not matching with your registered licenses in FMC.
