make you configured your DNS config on the switch :
ip name-server x.x.x.x
Do you have switch access to internet ?
if not you need to use your proxy to communicate with cisco license server.

So, I had the same issue and noticed I was missing the command below (compared with my other Cisco switches) and then added it:
ip name-server x.x.x.x
and then used this one:
license smart sync all
After this, the problem disappeared.
Thanks!

QuoVadis Root CA 2 Decommission and Transition to IdenTrust Commercial Root CA 1
Either upgrade the firmware of the switch or perform the workaround but do not leave this error message going because there is a memory leak with the "keyman" process.
