When trying to save a probe configuration update in Admin Console, the request fails with this type of error:
Message: Remote Request Error: Remote /redacted/probe/address/ probes processing of operation set_ctd_configuration failed
Resolution: Please check both the PPM and remote probe log file for additional details.
Error Code: PPM-012
Click Retry to retry the request.
Click Reload to refresh the configuration.
This is related to a corrupted or otherwise missing security.cfg setting.
1. Open Admin Console
2. Open 'Settings' --> 'Probe Security' (right side of the screen)
3. Set (or reset) access as 'admin' on the probe that can't save configuration
4. Close 'Probe Security' and refresh the admin console
