We have setup the integration between PowerBI and Databricks (hosted on AWS) using native databricks connector. However, we required Azure databricks connector to utilize the RBAC from unity catalog. We followed all the pre-requisite mentioned here , but still we are getting 404 connectivity error. 

Web.Contents failed to get content from "https://<>/oidc/custom/.well-known/openid-configuration' : 404 not found.

Could you please suggest and redirect me if we already have ongoing discussions on this issue. Many thanks in Advance
