Hello,
We are facing lot of issues with QV Connectivity and are constantly getting “Lost Connection to Server. Reconnecting”
This is posing a big problem for us with our customer. Everything seemed to be working fine but just three a few days back this started. The irony is that it happened during the demo and we were unable to control it.
This error happens randomly – sometimes it is working fine other times it just keeps on giving the “Lost connection” errors. We noticed that when the error starts - it particularly happens when we make the selections and press the search button. I have checked the internet connectivity and it seems fine. This happened a few times on the Server side also.
Will appreciate if someone can assist us with this as this is a real show stopper with the customer
Thanks.
There was nothing in our logs.
6 Months after reporting the issue Qlik finally came back with a fix:
Running Microsoft IIS
Handling Timeouts
Note! This is only needed when using very large QlikView documents that return timeouts.
Proceed as follows to handle timeouts:
Open the %ProgramFiles%\QlikView\Server\QlikViewClients\QlikViewAjax\web.config file in a text editor (for example, Notepad).
Search for the following text:<httpRuntime requestValidationMode="2.0" />
Edit the text so that it becomes:<httpRuntime requestValidationMode="2.0" executionTimeout="900"/>
Save the file.
Combining that time-out change with the QvsTimeout settings change above I've been able to prevent the "Lost Connection to Server. Reconnecting" errors when running large ad-hoc analysis. Needless to say I didn't leave positive feedback about the (lack of) support I got from Qlik.
Hi,
this one worked for me (our ticket at QSupport was open for 3 weeks with no helpful ideas)
Regards
this worked for me too, thanks one less headache
