Few issues from above screenshot to fix:

Kindly make sure to:

  1. A - issue could be here (sub-domain too deep - link from my previous post from above)

  2. CNAME ftp - switch it from :orange: to :grey: cloud (DNS-only)

  3. CNAME mail - remove this one

  4. Add a new record A mail with the content value of your server IP and make it :grey: cloud (DNS-only)

  5. Edit your MX to have the content value

  6. Add a new record A www with the content value of your server IP and make it :orange: cloud (proxied)

  7. Add a new record A with the content value of your server IP and make it :orange: cloud (proxied)
