Issue on creating an add-on domain in cPanel?

I am trying to create an addon domain in the cPanel but after installing WordPress, it's bringing me to this page, not on the WordPress Site. I added the domain on Cloudflare, using Cloudflare DNS, and added the server IP on Cloudflare. Does anyone know the solution?





Cloudflare Setting:

If everything is fine and the domain was correctly set up, then clear your browser's cache. cPanel error pages/redirects to error pages are very easily cached.

Also, turn on development mode in Cloudflare so such stuff doesn't get cached in Cloudflare.

Sometimes, it can take a few moments for cPanel to activate your domain, and it's possible the error page got cached.
