I've just upgraded to QlikView Server 9.0 SP2 and I'm getting the exact same error. I find it hard to believe there isn't a lot more clients getting the same error. When I connect to the server and hit the accesspoint locally on my company's LAN, I don't have any problems accessing my QlikView documents and viewing them using the IE Plugin or Java. But when I attempt to go outside the network and access the AccessPoint over the internet I can view the documents using the IE Plugin but not with the Java option. Has anyone found a solution to this?
One thing is for sure: Even if you don't have to install the java client it still runs on the workstation and has to connect to the server. According to the manual, the java client primarily uses port 4747, but it can fall back to the tunnel dll.
When I experienced the problem it seemed, however, that port 4747 was never even tried, and the "connection terminated" was due to the tunnel dll being incorrectly setup. What I did was
- add SCRIPTS -> C:\Program files\Qlikview\Server\QvTunnel to QlikView Web Server's list of root folders in QEMC.
- add qvstunnel.dll to the list of allowed web service extensions in IIS.
