Network connectivity and DNS resolution failures
Error:
java.net.UnknownHostException: bigquery.googleapis.com
or
Failed to connect to Google APIs: Connection refused
Cause:
These errors typically indicate that network policies are preventing the connector from resolving or reaching Google API domains. This commonly occurs when using serverless egress control without proper allowlist configuration.
Resolution:
Add the following Google API domains to your network policy allowlist:
bigquery.googleapis.comoauth2.googleapis.combigquerystorage.googleapis.comgoogleapis.com
For more information, see Manage network policies for serverless egress control.
