This could be due to the sls.conf file not being read or that the server MAC address is incorrect. Please check the following: 

  1. Confirm that the license file (sls.conf) is placed on the license server in: /usr/local/StarDrop/sls/var/run  
  1. Check that the license file is readable by user ‘nobody’. You can be checked with the command:  chmod a+r sls.conf 
  1. After this, please restart the license server with the command: /etc/init.d/StarDrop_sls restart 

If you are using the containerised servers, please copy the floating license file sls.conf to the license directory on your server. The default path is:  

/opt/stardrop/license/  

but you may need to replace /opt if you chose a different path for your installation.  

Finally, restart the license server by typing:  

systemctl restart stardrop-license  

If these steps do not resolve the problem, please send us the contents of the log file /usr/local/StarDrop64/sls/var/log/sls.log (legacy servers) or /opt/stardrop/license log/sls.log , to support@optibrium.com
