What frequency are reloads running for the app?

What option have you set on

Document Properties, Server, Refresh Mode when Document is Updated on Server
This setting can disconnect users.

I would set it to "Server performs refresh automatically without user action"

Refresh Mode when Document is Updated on Server

This setting defines how an updated document on the QlikView Server will be
handled.

Client initiates refresh. If old data not kept in server or client too old, session will be disconnected.	Choose this option if the server should never initiate a refresh of data in the client automatically. When a new version of the document becomes available on the server, the client will be offered to refresh according to the preferences set under Client Refresh Initiation Mode below. If this is not possible, either because the client is too old (pre version 😎 or if the server is set with Allow only one copy of document in memory enabled in the QlikView Server control panel, the session will simply be terminated.
Client initiates refresh. If old data not kept in server or client too old, refresh will be performed automatically	Choose this option if it is preferred to let the client initiate a refresh of data in the client when possible but will allow server to initiate a refresh automatically if necessary.

Check the server seesion time out setting. It might have to be increased.

QMC->System->Setup->Qlikview Server (select your server)->Performace-> Maximum Inactive Session time out (Default 1800 secs)

I have set my session timeout as 30 min (18000 seconds), but it is getting disconnected in 10-15 seconds.

Hi Logesh,

Can you confirm the affected user is not logged into the server via two different sessions using the same account details as this will also cause this error.

Hope this helps.

Kind regards,

Rod
