Port Listen: Failure on Port 4747

Mon, 26 Jan 2026 18:19:17 GMT

The server fails and when it try to restart the following message appears in the Events Log:

" Warning Port Listen: Failure on Port 4747

Error Init: The initialization process failed. Failed to capture port"

The telnet command on port 4747 works fine, so it has to be something else. It seems that the old session of the QVS Service is blocking the port.

If you want to stop the qvs service it gives time out. The only way out to this problem is to restart the windows server. I'm working with Qlikview Server 10 V 8811.

Any ideas?

Thanks,

Marco

It happened to me, too, anybody found the cause?

Log file:

Server Started Timestamp SeverityID EventID Severity Message

Event viewer:

The description for Event ID 300 from source QlikViewServer cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

If you add two FIrewall rules, Outbound and Inbound on the port, will that fix the problem? I usually add 4747 and 4780 for QEMC.

I was able to identify the service causing the port conflict using this tool: TCPView for Windows
