I would suggest to check the Securitygroups and make sure they match with:<BR /><BR /><A href="https://docs.databricks.com/en/security/network/classic/customer-managed-vpc.html#security-groups" target="_blank">https://docs.databricks.com/en/security/network/classic/customer-managed-vpc.html#security-groups</A><BR /><BR />Additionally check if the inbound and outbound addresses for the compute plane communication and properly whitelisted in your firewalls:<BR /><BR /><A href="https://docs.databricks.com/en/resources/ip-domain-region.html#databricks-control-plane-addresses" target="_blank">https://docs.databricks.com/en/resources/ip-domain-region.html#databricks-control-plane-addresses</A>&nbsp;</P> Mon, 04 Nov 2024 21:41:36 GMT https://community.databricks.com/t5/administration-architecture/compute-terminated-reason-control-plane-request-failure/m-p/97642#M2235 Walter_C 2024-11-04T21:41:36Z
