HTTP Response code: 302

When trying to access a Databricks Warehouse from an external workspace I get the following error.

Both, the Warehouse and the workspace are hosted on different AWS subscriptions.

But curiously, with the same script I can access the Databricks Warehouse from a workspace hosted in Azure.

I have tried and there is 443 connectivity from the workspace, but I receive this 302 HTTP error. It definitely looks like a connectivity issue, but I'm running out of ideas.

connecting to url [jdbc:databricks://XXXXXXXXX:443/default;transportMode=http;ssl=1;AuthMech=3;httpPath=/sql/1.0/warehouses/XXXXXXX;] and table [XXXXXXXXXXX]

SQLException: [Databricks][DatabricksJDBCDriver](500593) Communication link failure. Failed to connect to server. Reason: HTTP Response code: 302.

Caused by: ErrorException: [Databricks][DatabricksJDBCDriver](500593) Communication link failure. Failed to connect to server. Reason: HTTP Response code: 302.

Caused by: TTransportException: HTTP Response code: 302

I appreciate any help or suggestions, thank you!!

It is network related issue. Please check the private link, VPC peering, DNS names resolving to ip (from AWS and Azure), and routing of that IP inside AWS. You can also open a support ticket with AWS.

It was the DNS configuration of the VPC!

Thank you very much @Hubert Dudek !
