We don’t provide DNS services here at Render - that looks like you might be on the name server configuration page - you should look to configure DNS entries as opposed to changing the name servers in your control panel instead,
Thanks @John_B for your reply.
Ok, I think I understand that. Si I went to the cPanel of my DNS provider and created the CNAME and A records according to the documentation.
This time my question is, what now?
When I hit https://marcosdipaolo.com.ar should it redirect to marcosdipaolo-qos0.onrender.com?
As you can see, I really don’t understand about DNS, so please bear with me.
My thinking with mail. was to test other records from your provided screenshot to see if I could get them to resolve - I wasn’t able to.
It’s not the ns1|n2.allytech.com that needs to be changed here - those are the addresses of the DNS servers that hold the authoritative records for your domain - usually your domain registrar. You typically get a control panel to edit the records for your domain which are returned via those nameservers. It would seem that the changes you make in cPanel aren’t being reflected publically.
Your next steps here will be to work with your provider to understand why the changes in your cPanel are not being reflected on the public internet,
