Hi All,

We recently faced this issue wrt dataflow refresh and created a high severity support ticket with Microsoft since it was affecting 1000+ users in our company.

Upon investigating and troubleshooting we figured out that the gateway/ VMs were not able to access few IPs.

Please find the below response from the support team:-

" Just wanted to share latest update received from Product team and they wanted you to test some ip’s using Telnet or ping command on gateway installed server machine:-

The gateway logs clearly show an inability to connect to https://wabieurnorbcdsa.blob.core.windows.net/

Since "Ping" is not ubiquitous any more, you can test connectivity by using telnet. A web page that explains how to do this is here: https://support.n4l.co.nz/s/article/How-to-use-Telnet-to-Check-the-Status-of-Ports

From the Gateway machine, attempt to make a telnet connection to port 443 on each of these hosts:

• wabieurnorbcdsa.blob.core.windows.net
• 20.60.40.69
• 20.60.40.100
• 20.60.40.132"

Troubleshoot the gateway as suggested above and ask your Network admin team to whitelist IPs. This resolved the issue for me.
