problems with domain

Hello,

I have a problem.

Installed Virtualmin on my VPS. IP: 5.199.167.158

created subdomain: server.sekonas.com. System working if i go to: https://server.sekonas.com:10000/

It’s ok!

Now, i created another sub-domain, called mailas.sekonas.com

It’s ok to connect to ftp. But when i go to mailas.sekonas.com it shows only Apache message, nothing else.

I was trying to upload index.html to public_html dir, but not work… Where’s the problem?

Thx for answers…
