model checkup is done without checking a license. there are many license types, so you should inquire the distributor about which you have, or try every option mentioned above.nbut sometimes the license server just does not work or freeze licenses. it is a big problem existing from the beginning of flexlm. it is simply not reliable in big networks.nso check the debug logs at the server, and see, did your client really tried borrowing a license? if yes, what was the real reason of failure? if not, check IP packets passing, firewalls, router etc.n
