I may order another VPS to setup a Slave DNS Server in future. Making Changes at the Domain Registrar ======================================= Login to your domain registrar. In my case it is namecheap. On the left menu, click Domain List. Check domain name turritopsis-dohrnii-teo-en-ming.com and click Manage. Click Advanced DNS. Scroll down to PERSONAL DNS SERVER. Click ADD NAMESERVER. Nameserver: NS1 IP Address: 185.182.9.61 Click DONE. Click ADD NAMESERVER. Nameserver: NS2 IP Address: 185.182.9.61 Click DONE. After adding your two name servers, click the search button to check if they are added successfully. If so, the glue records will appear at the bottom of this page. Now, click the Domain tab. Under NAMESERVERS, select Custom DNS. Nameserver 1: ns1.turritopsis-dohrnii-teo-en-ming.com Nameserver 2: ns2.turritopsis-dohrnii-teo-en-ming.com Click the green check mark. Sign out from namecheap.

Domain name: turritopsis-dohrnii-teo-en-ming.com Description: Turritopsis Dohrnii Teo En Ming's Domain Administration password: <REMOVED> SSH public key: No default key Server configuration template: Default settings Account Plan: Default Plan Administration username: Automatic Enabled features ================ Check Setup DNS zone Check Setup Apache website Check Setup Apache SSL website Check Create MariaDB database Check Accept mail for domain Check Setup spam filtering Check Setup virus filtering Check Setup Webalizer for web logs Check Create Webmin login Check Enable AWstats reporting Uncheck Setup IP-based virtual FTP Click Create Server Error ===== Failed to create virtual server : The DNS domain turritopsis-dohrnii-teo-en-ming.com is already hosted by your DNS server Click Return to previous page. Attempt to Create Virtual Server for the 3rd time ================================================= Login to Virtualmin. Click Create Virtual Server on the left menu. Domain name: www.turritopsis-dohrnii-teo-en-ming.com Description: Turritopsis Dohrnii Teo En Ming's Domain Administration password: <REMOVED> SSH public key: No default key Server configuration template: Default settings Account Plan: Default Plan Administration username: Automatic Enabled features ================ Check Setup DNS zone Check Setup Apache website Check Setup Apache SSL website Check Create MariaDB database Check Accept mail for domain Check Setup spam filtering Check Setup virus filtering Check Setup Webalizer for web logs Check Create Webmin login Check Enable AWstats reporting Uncheck Setup IP-based virtual FTP Click Create Server Error ===== Failed to create virtual server : The domain name does not need to have www at the start Final Thoughts ============== Hmmmmmmmmmm, I cannot create virtual server using my domain name turritopsis-dohrnii-teo-en-ming.com after configuring DNS using Webmin manually. It looks like I need to configure custom DNS servers at my domain registrar first, then create virtual server, and then fine-tune DNS records. I shouldn't configure DNS with Webmin manually. This is my very first time setting up Virtualmin and Webmin, so I am not that familiar with the setup process.
