Problem with fresh install

I’m unfamiliar with server admin stuff so followed a Youtube tutorial (Create a High Performance Web Server (CyberPanel/OpenLiteSpeed) for WordPress in 10 minutes - YouTube) to install Openlitespeed and cyberpanel on Linode Centos8 server. All seemed to go well but nothing responds at the ipaddress.

The terminal console shows an error (Imgur: The magic of the Internet), but I have no ideas what my next steps should be.

Any help greatly appreciated…

Tried restarting the server - no change

Tried deleting the linode and going through the process again, but not deselecting the option for watchdog (beta) - no change

Tried again, deleted existing linode and used ConOS7 this time. Same problem, connections timed out - but this time I tried the reload option in the browser and hey presto it worked. Might have worked with contos8 the first time I don’t know.
