Hi Team,  
Not sure it is right place to ask this.  
We have closed environment which is not exposed to internet. And I have configured to send logs to Azure Data Explorer via Logstash Kusto output plugin.

We allowed traffic on ADX private endpoints.  
Also to authenticate via Entra App, allowed below urls at Logstash.

- [https://login.microsoftonline.com](https://login.microsoftonline.com)
- [https://login.windows.net](https://login.windows.net)
- [https://login.microsoft.com](https://login.microsoft.com)
- [https://sts.windows.net](https://sts.windows.net)

As it was showing Uploading failed to blob storage, we allowed outbound traffic to public IP addresses of blob storage

- **Pv4 ranges** :
  - 13.107.6.0/24
  - 13.107.9.0/24
  - 13.107.42.0/24
  - 13.107.43.0/24
  - 150.171.22.0/24
  - 150.171.23.0/24
  - 150.171.73.0/24
  - 150.171.74.0/24
  - 150.171.75.0/24
  - 150.171.76.0/24

- **IPv6 ranges** :
  - 2620:1ec:4::/48
  - 2620:1ec:a92::/48
  - 2620:1ec:21::/48
  - 2620:1ec:22::/48
  - 2620:1ec:50::/48
  - 2620:1ec:51::/48
  - 2603:1061:10::/48

I am able to telnet to everything mentioned above but still facing Uploading failed error at Logstash. I am not able copy content from that close environment that's why attaching screenshot of error here.

Not sure what else need to allow at firewall to successfully ingest data.

Thanks,  
Disha
