Please make sure the port for the ansyslmd daemon is open on the license server firewall. The error seems to indicate a problem with communicating with ansyslmd.
You can set ansyslmd to a static port by adding it in the license file on the VENDOR line. Then restart the license manager and ensure the firewalls are updated to allow the port.
VENDOR ansyslmd PORT=1056
If running only the Windows firewall on the server/host machine, please review this video for how to add exceptions for the executable files.
