KB: Cannot use a private license as the seat is occupied

Solution Details

If all seats of private license are occupied inadvertently, an administrator can still log into the server machine directly where the on-premise server software is installed (Vault/Nexus Server/Concord Pro/AIS/AES) either locally or via remote desktop to release the seat through a web interface.  Type the address 'http://localhost:9780' in a web browser.  Default username/password are: admin/admin.  Expand Admin - Licenses, select the license and click 'Release'.

 
 
Remotely accessing the server requires a CAL (Client Access License), which is occupied most probably, so please make sure you are at the server's machine where the server software (Vault/Nexus Server/Concord Pro/AIS/AES) is installed.

For further details, please refer to manual pages for respective on-premise server software:
