Resolution
The possible causes of this issue are:
Service Account Group Membership Missing
The service account is not a member of the local Administrators and/or the QlikView Administrators security groups and/or the account is added into the group but is not reflected in the Operating System yet.
Note: After the initial installation of QlikView, reboot the host machine to ensure the security groups are correctly applied.
Service Account Permissions
The service account used does not have the required permissions to let the services communicate. It may not be allowed to run as a service or have required permissions blocked by domain policies.
This includes access to the QlikView Server ProgramData folder.
To troubleshoot:
- If a domain account is used:
- Create a local account
- Add it to the QlikView Administrators and local Administrators group.
- Change the service account used
- Test
- If a local account is used:
- Change the currently used service account to Local System
- Test
Application Data folder permissions or corrupted data
The Application Data folder (C:\ProgramData\QlikTech) may have some corrupted files or security-related issues.
Servername exceeds 15 characters
Windows does not allow for server names beyond 15 characters.
Blocked Ports
The QlikView Server service TCP port 4747 may be blocked. This can happen in a single node server as well as distributed implementations, be sure to confirm firewall settings on the server(s) allow communication between the services over the port.
Kerberos encryption method RC4_HMAC_MD5 is disabled on the Server
