Domain or subdomain for server hostname?

[gkarea]

Hello, My main website is domain.com want to host on vps with myvestacp..
what i choose for myvestacp admin panel while installing myvesta as fqdn ? Whould it be like.. server.domain.com or simply domain.com for admin panel?

currently I have set up fqdn while installing myvesta as domain.com.. is it fine??? or should i use something like server.domain.com or srv.domain.com..
Thanks...

server.domain.com is my recommendation.
it's always better to have separated hostname for server.

If i set as server.domain.com. then my name servers will automatically included ns1.server.domain.com and ns2.server.domain.com in the admin panel.. Then how can i use name server like ns1.domain.com and ns2.domain.com with fqdn as server.domain.com??? Thanks for your replay...

Actually I want to set up host as server.domain.com as fqdn and name server are like ns1.doman.com and ns2.domain.com... Can I use like this??

You are right.

Well, you can manually add ns1 and ns2 (as A record) to your domain after installation.
Everything other will works.
You can also generate LetsEncrypt for hostname later... it will be automatically applied as general SSL then.

I have tried as you said but ssl is not generating showing 400 error..

Do not post password and IP address on this public forum.
I will take a look now.

I am just testing this server..... Please inform me what was my fault..

Probably too many unsuccessful attempts to generate LetsEncrypt, and now you are blocked by LetsEncrypt, probably within 24 hours.

Maybe www. alias was the problem, I removed it now.

Try tomorrow to generate LetsEncrypt.
