NPIP tunnel setup failed [WaitForNgrokTunnel]

[sp334]

Hello All,

We have deployed a new databricks instance in Azure cloud

1) Databricks service attached public subnet/private subnet (delegated to Microsoft.Databricks/workspaces)

2) i created a job with cluster runtime ( 1 worker: Standard_DS3_v27.3 LTS (includes Apache Spark 3.0.1, Scala 2.12))

3) Tried to start the job , but it's failing with below error message

</ Run result unavailable: job failed with error message Unexpected failure while waiting for the cluster (1XXXXXXXXXX) to be ready.Cause Unexpected state for cluster (1XXXXXXXXXXX): NPIP_TUNNEL_SETUP_FAILURE(SUCCESS): databricks_error_message:NPIP tunnel setup failure during launch. Please try again later and contact Databricks if the problem persists. NPIP tunnel setup failed [WaitForNgrokTunnel] />

4) I found a pattern here after multiple job failure , each job is taking around ~ 2 mins 20 secs to fail

please let me know anyone had similar issue in the past or have some inputs?

Can you please review the network setup with https://docs.microsoft.com/en-us/azure/databricks/security/secure-cluster-connectivity . May be azure support can help you out on this if it continuously failing .But this looks like the network setup issue . @kiran 334​

In case others run into this in the future. Here is something additional to check:

• Is your account/workspace enabled for the "compliance security profile"?
• If yes, you should see a little shield icon in the lower left-hand corner of the workspace
• Once you confirm it is enabled, a reason that you may be experiencing this is due to the incomplete setup of your workspace as it relates to the compliance security profile
• As part of the setup, check that outbound port 2443 has been added

Good luck!
