Unable to start QVS Service - Status Message: Off Duty

The Qlikview Server service will not start after applying a license to the Server. It shows as "Off Duty" with no license shown in the Management Consolde. No errors are found in the logs.

This issue occurs when a license is already in use by another server in the same network.  And it also occurs if two or more servers are sharing the same license, but this license does not allow clustering or the number of cluster nodes is exceeded. 

Adding to above, there are also other possibility to cause this issue such as QVS Folder corruption.

Go to QMC > Status > QVS Statistics > Performance. Check OffDuty tag and check the message.

• Check to make sure no other servers are in use in the same network
• If setting up a clustered environment, make sure that the license is setup for clustering and has the correct number of nodes in the LEF. The entry in the LEF will look like this:NUMBER_OF_CLUSTER_NODES;X where X is 2 or higher
• If two or more nodes in License, check that all have the same Root Folder
• As above, verify if the settings.ini file has the correct root folder path configured
• QlikView Server (QVS) Folder Corruption. Stop QVS Service, Remove or rename QlikView Server Folder (C:\ProgramData\QlikTech\QlikViewServer) and Restart QVS Service again. 
• Service Account should be the domain user across the nodes (assuming Service Authentication method: QlikView Administrators Group)
