can't connect to cluster in ADX

Question

Hi, I'm trying to connect to my adx cluster to ingest data from ADLS Gen2 but for some reason, it's failing with the error(Failed to connect to cluster. Please verify the URI.)
The URL I've entered is a valid URL as you can see in the screenshot below.
What can I do to resolve the issue?

Hello @Yu, Hazel (APEX SYSTEMS LLC) ,

Thanks for the question and using MS Q&A platform.

Were you able to connect to the same cluster in the past using the same URL or is this the first time you are accessing it?

I would recommend following the below steps for verifying that you have all required permissions to that cluster.

Hope this helps. Do let us know how it goes.

Thank you

Is ADX deployed in Vnet by any chance? As far as I know, Data Explorer Web UI can't connect to Vnet isolated clusters unless access from Web UI (internet?) to cluster is allowed in subnet NSG.
