Troubleshooting
This section describes how to handle the issues that you might face when using CTE with the CipherTrust Manager.
Connection Issues
| Symptoms | Possible Cause and Remediation | 
|---|---|
| • Client status is Error • Configuration changes are not pushed to the client • Requests like Browse file system are failing | Analyze the CTE logs, identify connection failure reasons, and rectify them: 1. Look for the issues in the /var/log/vormetric/server_comms.logfile on the CTE agent. This file contains information about the CipherTrust Manager's communication with the client.2. Identify the cause of the issue. 3. Restart vmdto get the latestinit. | 
Registration Issues
| Symptoms | Possible Cause and Remediation | 
|---|---|
| Registration fails with conflict errors | Conflict errors occur when a client with the given name already exists on the CipherTrust Manager. To fix these issues: • Delete the existing client entry from the CipherTrust Manager. • Unenroll the existing client if you want to register it with another CipherTrust Manager. NOTE: A conflict error might occur even if no CTE client with the given name exists on the CipherTrust Manager. To resolve the issue: 1. Check for the client name under Client-Management: Clientsin the API playground.2. Delete the client from the list. 3. Retry registration with the same name. | 
| Reregistration fails with capabilities related errors | Capabilities cannot be disabled during reregistration with the CipherTrust Manager. To disable the CTE Agent capabilities, delete the client from the CipherTrust Manager and register again with these capabilities disabled. | 
Backup and Restore Issues
| Symptoms | Possible Cause and Remediation | 
|---|---|
| Reregistration issues after CipherTrust Manager is restored on a new CipherTrust Manager appliance | After the backup of a CipherTrust Manager is restored to another CipherTrust Manager, CTE client reregistration does not work as expected. To work around this issue: 
 | 
Licensing Issues
| Symptoms | Possible Cause and Remediation | 
|---|---|
| • Registration fails with licensing errors • LDT feature cannot be used • CTE configurations are read-only | Registration can fail if the number of purchased licenses are consumed or the validity of a license is expired. This is applicable for all types of licenses: the base license (CTE - TransparentEncryption), the CTE for Kubernetes license (CTE - KubernetesProtection), and the add-on license (CTE - LiveDataTransformation). • To enable LDT at the time of registration (or later), make sure that you have a valid base license and a valid add-on LDT license. • After a license is expired: – A new client cannot be registered. – Existing operations on registered clients remain in tact. Their existing security configurations are pushed as and when required. | 
Configuration Issues
| Symptoms | Possible Cause and Remediation | 
|---|---|
| Mismatched log levels between the CipherTrust Manager configuration and client logs | Try these: • Check the configuration in the linked profile on the CipherTrust Manager. • Validate the vmd configuration on the CTE client by running: vmsec vmdconfig |
