Databricks App OAuth token request failed: {exc}

Error message

Databricks App OAuth token request failed: {exc}

What it means

Raised in the Databricks App OAuth client-credentials flow when the token request fails with an httpx error other than HTTPStatusError — i.e. a transport-level failure: connection refused, DNS failure, TLS error, or timeout hitting config.token_url. The original exception is chained. HTTP-error responses have their own separate wrapper with the status code.
