The "Cannot connect to license server system" variation of the "Invalid or missing license file" errors occurs on a computer running Maple that connects to a license server to check out a license.
If this error occurs, it is likely that the client computer can not reach the Maple license server.
- If your school or workplace requires a VPN connection to reach their license server, ensure that your device is connected to the VPN.
- Ensure that the license manager service is started or restarted in LMTools on your license server.
- Ensure that the lmgrd and maplelmg ports are open on the network.
