00;31 second failed timeout for Dataflows Gen 1 with Redshift Connection

[rtylerr]

Hi all

I connect to my redshift cluster through a gateway, the data loads in dataflow preview, then when I go to refresh in the workspace i get an error, a random activity id throw up in the excel output - and it usually is 00;31 seconds before it fails everytime.

Is this a gateway issue?

Helpppp

Thanks

Hi @rtylerr ,

Thank you for reaching out to the Microsoft Fabric Community Forum.

Since the preview loads but the refresh consistently fails around 00:31 seconds, this usually suggests a network timeout on the gateway path rather than an issue with Fabric Dataflow. Please check the gateway host's firewall or proxy settings and make sure there isn’t a 30-second idle or session timeout for outbound connections to Redshift. Dataflows Gen2 has better network management, so switching to Gen2 is recommended if possible.

Thank you.
