How to Fix cpanel-ccs Failed
Check the output from "/usr/local/cpanel/scripts/restartsrv_cpanel_css" command for the following:
ccs_init[19307]: Pidfile /opt/cpanel-ccs/data/Logs/state/caldavd.pid contains non-numeric value
If this message exists, this indicates that the "caldav.pid" file may be empty.
Verify the cPanel CalDAV server status by running the following:
sudo systemctl status cpdavd
If the output from the above command indicates the server is not active, this would cause the cpanel-ccs server failure. To fix this issue and attempt to resolve the cpanel-ccs failed error, run the following commands:
/scripts/restartsrv_cpdavd —restart sudo mv -v /opt/cpanel-ccs/data/Logs/state/caldavd.pid ‘/opt/cpanel-ccs/data/Logs/state/caldavd.pid’ -> ‘/opt/cpanel-ccs/data/Logs/state/caldavd.pid-bak’ /scripts/restartsrv_cpanel_ccs --start
