The error-message your providing is indicating that 4747/TCP isn't open between client-server. There are several ways to verify connectivity between client-server before digging further into other areas.

Easiest way is to use TELNET on the client and try establish a connection to the server:

- Open a command prompt and type:

Telnet ip-number-to-qvs 4747

If the connection is successful you will get a blinking cursor in the command prompt. Otherwise you will receive a connection error.

If connection is successful with the telnet-test, 4747/TCP is open.

The next step would be to activate ExtendedErrorLoggingMode on the client:

- Launch IE and go to qvp://demo.qlik.com to launch the plugin. Open any document
- In the toolbar hit Menu - About QlikView
- On the About dialog right-click the Q-icon at the botton left. This will open up some hidden settings
- Locate ExtendedErrorLoggingMode and set the value to 1. Don't forget to press "Set"
- Close IE to make sure the plugin is released
- Open IE and try again to connect to your server. It will fail, but now you will get a logfile in the Documents-folder for the currently logged on user. The log will be named QlikViewError.log

Analyzing the log might give you further clues to why the client is not able to connect.

The reason for the issue is in the error:

"2010-08-02 12:26:23 Warning Connect .\EasySocket.cpp 403 Could not resolve hostname "............" 11001 No such host is known."

The client cannot resolve the hostname to the server. If you're trying to connect to qvp://qlikview the client must be able to resolve the host "qlikview", i.e. it must be registered in the DNS. Easiest way to check resolution is to try to ping the server using the host name.

If you want to change the host generated in the qvp-link, edit config.xml for QlikView Web Server and change LinkMachineName.

The alternate is to use the server's web pages to load the qvw:

http://server/QvPlugin/opendoc.htm?document=docname.qvw

I had the same problem.

Opening port 4747 (making exeption in firewall) wash the solution for me!

Hey

I had the same problem and the LinkMachineName Setting in the config.xml from the webserver was my solution.

It's also possible to fix this problem with an etc/hosts hack. You have to add your internal server with the external ip to the etc/hosts file on the client pc. I get this fix from the Qlikview support. But if the IP or the hostname changes you have to update all hosts files.

My question is, why is the LinkMachineName setting not reachable from the Enterprise Console? And why is there the wrong hostname?

Best wishes

Bastian

Hey, i have the same problem but SimonD post was the solution to solve it. I open the port 4747 on my firewall and setup the router also to port forward connections to 4747 port to the server.

Thank you very much!

Hi Ivan,

I had the same problem even using VPN, and I've just enable port 4747 in the firewall icoming and outgoing rules and now works (rull applied and firewall enable)

Hope this works for you as well,

Have a nice day,
