QlikView AccessPoint to Server timeout: Lost Connection to Server Reconnecting

Opening, or navigating in, a QlikView document using the Full Browser Client leads to "Lost Connection to Server, Reconnecting" messages. The Timeout is set correctly in the WebServer config.xml file. 

Reviewing the QlikView WebServer log files located in %ProgramData%\QlikTech\WebServer\Log shows 

Warning    Connection lost. Reconnect to server: qlikserver1
The following timeout values have already been increased:
  • %ProgramData%\QlikTech\WebServer\config.xml: <QvsTimeout>600</QvsTimeout>
  • QlikView Management Console > System > Setup > QVS@server > Performance > Document: Object Calculations Time Limit


  • QlikView 12.20 (November 2017) and later
  • QlikView 12.10
  • QlikView 12.00
  • QlikView 11.20 SR12 and later



An additional value needs to be increased. It overrides the current QvsTimeout setting.

If using QlikView Web Server:
  1. Stop the QlikView WebServer Service
  2. Navigate to C:\Program Files\QlikView\Server\Web Server
  3. Open QVWebServer.exe.config
  4. Inside the <appSettings> section, add the following key (if not already present): 
  5. <add key="SocketTimeOutInSeconds" value="600"/>
  6. Save the file, and start the QlikView WebServer Service

If using IIS:

1.  Open IIS manager on the web server
2.  Highlight the Default Web Site (if not using Default Web Site, select the web site which was chosen during the QlikView Settings Service installation process)
3.  Double-click Application Settings
