Hi, We have identified that some machines (MacOS) are not received the license from our server, after troubleshooting we ran the command: sudo /Library/Application\ Support/Kaspersky\ Lab/klnagent/Binaries/klnagchk And in affected machines we receive the following answer: Starting klnagchk utility Checking command-line arguments...OK Initializing basic libraries...OK Current host is 'ecrmac.fios-router.home' Network agent version is '12.0.0.35' Reading settings...OK Checking settings...OK Administration Agent settings: Server address: 'securitycenter.e-core.com' Use SSL: 0 Compress traffic: 1 Server SSL ports: '13000' Server ports: '14000' Use proxy: 0 Certificate: absent Open UDP port: 1 UDP ports: '15000' Ping period, minutes: 15 Conn timeout, s: 30 RW timeout, s: 180 HostId: Connecting to server...Transport level error in process of connection to 'http://securitycenter.acme.com:14000': connection refused Connecting to the Administration Agent...OK Administration Agent is running Acquire Administration Agent statistics...OK Administration Agent statistics: Ping count: 0 Succ. pings: 0 Sync count: 0 Succ. syncs: 0 Last ping: Deinitializing basic libraries...OK We have around 300 MacOS devices with Kaspersky installed and this issue(not receiving the license, and getting the error message) only happens in few devices. What we have tried: Restarting KSC Server Double checking the open ports in the server Asking the device owner to restart/change networks Thank you.
