hostname ssl cert can be reason for not starting cwp, you can try .
(run as root)
Try to run:
sh /usr/local/cwpsrv/htdocs/resources/scripts/generate_hostname_ssl
Then:
sh /usr/local/cwpsrv/htdocs/resources/scripts/restart_cwpsrv
If won't work after that, check if /etc/pki/tls/certs/hostname.crt exist (it should be symbolic link linked to hostname sub.domain.tld.crt located in the same ...certs/ directory).
