Welcome to Microsoft Q&A platform and thanks for posting your query here.

This error typically occurs when the cluster setup process takes too long, often due to network delays, resource allocation issues, or communication problems with the cloud provider

Here are some steps to troubleshoot this issue:

Check Databricks Service Status: Verify if there are any known issues in your region by checking the Databricks service status page for Azure

Allowlist Required Services: Ensure that all required Databricks Fully Qualified Domain Names (FQDNs) and IPs are allowlisted in your Virtual Private Cloud (VPC) or Virtual Network (VNet). This includes control plane IPs, metastore, artifact blob storage, system tables storage, log blob storage, and event hubs endpoint.

Verify VPC/VNet Configuration: Make sure that your VPC/VNet configuration meets all the requirements for customer-managed VPC/VNet for all subnets used with Databricks.

Check Firewall Settings: Determine if there are any throttling issues observed in the firewall. If your workspace has a private link enabled, verify that the DNS is enabled and in the approved state.

Retry Deployment: Sometimes, this error can be a temporary glitch. Retrying the deployment might resolve the issue.
