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.
For example:
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.
