Hi @arsalaan ,

 

In terms of Redshift, please check: 

1) Wrong hostname or port

2) Publicly Accessible is set "NO" in your Redshift cluster configuration (Only VPC)

If you launched your Redshift cluster in VPC, Publicly Accessible: needs to be YES to access from outside VPC.

3) VPC security group is not configured correctly

There are two patterns to setup security groups to access Redshift.

  • Non-VCP: Redshift Securiy group settings
  • VPC: VPC security group settings

Check if you setup the correct security group settings along with the place where you launched your Redshift cluster.

 

Besides, in terms of PBI you can check the following settings:

1)Check if the gateway is installed and working properly.
2)Optimize the query or reduce the amount of data to be refreshed.
3)Refresh the data during off-peak hours when the data source is less busy

 

For more details, please refer to:
