Centos Web Panel Login Problem

Hi,

I installed centos 7 and cwp7 today. Its really so nice and easy panel. I like very much.

I created a domain and I have it on godaddy. When i try to change nameservers, its not working ns1.mydomain.com and ns2.mydomain.com and i try to use dns options and i can reach my server now.

when try to open mydomain.com:2082, opening login page. When i write username and pasword for domain, waiting login page. Cannot logging in. How can i solve that problem?

Another problem is mail server. I write my ip on free dns manager mail area. When i try to open mail.mydomain.com, opening homepage. Roundcube mail not opening. I try to open from cwp root panel but not working too. What should i do?

Last question, i created subdomain and its demo.mydomain.com but its not opening too..

thanks for help..

Hi
With installing options you must first setup Hostname

1.This hostname cannot be the same as any domain that is on your server (for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).

You can use the following command for hostname setup eg. srv1.example.com

hostname srv1.example.com
2. Setup Server IP addresses
Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information.

if you setup properly, you need to be sure that your domain is forwarding on the IP address of the server for example
doman.com > 123.123.123.123.

If everything is set up properly, try using the ip address to log in ex. 123,123,123,123:2030

And Check Fast Login (no stats and checks)
