"-129 =" error when working on the Qlik Management Console (QMC) on Qlik Sense Enterprise for Windows

[Sonja_Bauernfeind]

When working on the QMC, users see a "-129 =" error.

Environment:

• Qlik Sense Enterprise on Windows , any

Cause:

Most probably this indicates a timeout and there is some steps to follow to change this max value.
Probable root cause could be the delay of a task that is being executed and needs more time to finish.

Resolution:

If you are already tried to refresh the and reload again without success, you can try these next steps:

1. Open the QMC 
2. Go to Editing a Virtual Proxy
3. Select Virtual proxies on the QMC start page or from the StartS drop-down menu to display the overview.
4. Select the virtual proxy that you want to edit and click Edit in the action bar.
5. Increase the value in the field "Session inactivity timeout (minutes)"  as an example you can change the value from 30 to 60
6. Click Apply to save your changes
