Hi Antonius,
Seems when your machine is in sleep mode network card owning the license host ID is getting inactive and on machine wakeup, service for license manager is not starting (as Network card was down).
You may try the below steps:
1. Select Start > Right Click on Computer > Manage
2. Double click on Device manager > Expand Network adapters
3. Select Appropriate network card in the list > Right Click > Properties
4. Select Power Management tab > Uncheck "Allow the computer to turn off this device to save power" > Ok > Close Device manager.
This will disabling the network card on sleep mode and when machine will wake up, service will start on own as network card will remain active.
I hope this will help.
