## Symptoms

- Security Gateway or Cluster Member is missing from the CDT Candidates List.

## Cause

The "`cprid_util`" process on the Management Server is unable to connect to the "`cprid`" process on the Security Gateway over the TCP port 18208.

Example from the */var/log/CPcdt/logs_\<YYYY-MM-DD-HH-mm-ss\>/Main_log.elg* file on the Management Server:
> `Mon Sep 19 18:17:57 2022 *D*: Querying object MyGW.`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Object is VSX.`  
> `
> Mon Sep 19 18:17:57 2022 *D*: IP xx.xxx.xx.xx`  
> `
> Mon Sep 19 18:17:57 2022 *D*: The machine has more than one member object. Retrieving members...`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Adding member MyGW IP xx.xxx.xx.xx to cluster MyGW IP xx.xxx.xx.xx`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Adding member MyGW IP xx.xxx.xx.xx to cluster MyGW IP xx.xxx.xx.xx`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Finished retrieving members of MyGW`  
> `
> Mon Sep 19 18:17:57 2022 *D*: ClusterXL detected as VSX`  
> `
> Mon Sep 19 18:17:57 2022 *D*: VSX ClusterXL detected as VSLS`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Cluster type of MyGW is 3`  
> `
> Mon Sep 19 18:17:57 2022 *D*: Adding machineMyGW to the list of database objects.`  
> `
> `  
> `
> Command Summary:`  
> `
> Command = cprid_util -server xx.xxx.xx.xx getarch`  
> `
> `Return code = 3  
> `
> Output = unknown`  
> `
> `  
> `
> Mon Sep 19 18:17:57 2022 *D*: OS of a cluster member (cluster IP xx.xxx.xx.xx) is not supported or machine is offline. Skipping.`
