To work around this issue, leave the FQDN field blank, uncheck "Start Cluster," and then add the desired IP in the FQDN field of the Open OnDemand cluster's settings in the CycleCloud web UI. |
| 51 | +- **Azure US Gov Only**: Marketplace deployment validation fails due to an incorrect API version. To mitigate this issue, refer: [How to deploy a CycleCloud Workspace for Slurm environment using the CLI](../../how-to/ccws/deploy-with-cli.md). |
