How to transfer ssl certificates from Debian/Apache2 to Openlitespeed Webserver?

[Pidl]

I'm trying to transfer my existing SSL certificates from Debian/Apache2 to Openlitespeed Webserver

These are the current paths to the certificates on the current configuration on the Apache2 . server
SSLCertificateFile /etc/ssl/certs/my-domain_com.crt
SSLCertificateKeyFile /etc/ssl/certs/my-domain_com.key
SSLCertificateChainFile /etc/ssl/certs/my-domain_com.ca-bundle

I've checked the instructions on this page:
https://openlitespeed.org/kb/ssl-setup/#Specify_SSL_Key_and_Certificate

It does't work and "sudo lsof -i -P -n | grep LISTEN" doesn't show any entries for port 443
I'm attaching a screenshot of my set up

Thanks

To anyone who may be interested.
Issue was due to invalid cert path, so port 443 listener failed to start.
