2 days in a row now my users call me saying that when they login to the liquidfiles server it says that the license is invalid or we don't have enough licenses for our user count. When I go to System - License my license code is there but the Licensed Hostname is blank. if I click Update it will fill out the hostname and everything will go back to normal. Until the next day. Is this a bug or a misconfiguration? How do I get it to stop dropping the license?
