Hi @t-saito,
Not exactly sure what happened here.
Can you please remove /etc/httpd/conf.d/zzzkaltura.ssl.conf and /etc/httpd/conf.d/zzzkaltura.conf, restart Apache, ensure it is up and running and then re-run the config scripts?
If SSL is desired, PROTOCOL should indeed be set to “https”. If after doing this, you’re still having issues, please post your auto generated answer file here [it is saved under /tmp/kaltura_$TIMESTAMP.ans every time you run the config scripts. Of course, be sure to mask sensitive information before posting.
Thanks,
