It didn’t allow me to add an A record using the IP address, but it worked when I tried editing it. So now it looks like in the screenshot. Is this correct now?
If those are the records Hostinger has asked you to set, then that should work.
Once it is working you may be able to switch the records to “Proxied” - without that any Cloudflare features or protections set in your account won’t be applied as requests will go direct to Hostinger.
I talked to Hostinger and they suggested I remove the CNAME record so that is what I did. The DNS propagation looks completed to me, but the Hostinger website insists that the domain isn’t connected. Should I turn proxy on then?
