Error loading data

[xyz_1011]

Hey all,

i am loading data from an on prem ORACLE database via Qlik Data Gateway. I constantly get the following error with one of our bigger tables (> 20M records):

(Connector error: Reload web socket was aborted due to a failure (DirectAccess-1103))

Any idea how to do to fix this ?

Thanks in advance!

Thanks @anat but i am not sure this helps.

We are running on Qlik Sense SaaS and i am getting this error regardless from where i trigger the script. I.e., even when i do this via an automation on schedule (with no window open or active connection to the tenant...). I wouldnt know where / how to check web sockets settings...

Thanks!

hi there, did you manage to solve this? I am getting the same error: we use qlik sense saas cloud.

Connector error: Reload web socket was aborted due to a failure (DirectAccess-1103

but couldnt find enough material to know what is really about... I am thinking it may be because of our connection between qlik gateway to our Oracle servers ... but not sure of it and how to proceed to correct this issue. they happen once every one day or two, with random ETLs

Anyone found the resolution for this?

we are also seeing this on Qlik Cloud Government (a version of Qlik Cloud) and have not found the root cause yet.

Hi @Ken_T,

Did you find a solution?

I'm facing the same issue:
"Error: Internal error. (Connector error: Reload web socket was aborted due to a failure (DirectAccess-1103))".

It happens randomly, and with different reload apps.

I have to manually reload the task.

Thank you.

Hello , Did anyone find  the solution of this error

[Ken_T]

we are still seeing this, not very often but no root cause found yet.  about 20 occurrences this year so far (April 2026)

Hello @xyz_1011, 

Here some causes and solutions to help you.

1. WebSocket timeout
The reload takes so long on tables with 20M+ records that the connection times out before it finishes. You can increase the timeout directly in the Qlik Data Gateway configuration file (appsettings.json) or via the QMC. Look for the ReloadTimeout and WebSocketTimeout settings.

2. Memory or buffer limit
Very large tables can exceed the default buffer size. In your Qlik script, consider:
  • Adding a WHERE clause to load data in smaller slices (e.g., by date range or ID range)
  • Implementing incremental loading using QVD files as an intermediate layer

3. Outdated Data Gateway version
The 1103 error has been resolved in several versions of the Qlik Data Gateway — Direct Access. Please verify that you are running the latest version by going to Qlik Cloud Console → Data Gateways.

4. Network or proxy configuration
The WebSocket connection may be getting dropped by an intermediate proxy or firewall. Confirm that long-lived WebSocket connections are allowed between the Data Gateway server and Qlik Cloud.

5. Oracle ODBC/JDBC driver
An outdated or misconfigured driver can cause connection drops when handling large data volumes. Validate the Oracle driver version installed on the Gateway server.
