I have bought a domain and I want to use multiple subdomains for different sections of my application. I want the server to have it own subdomain i.e. server.example.com, I want the landing page to have the URL of the domain i.e. www.example.com and I want to have the web application have the subdomain app.example.com.
To point the server subdomain to the host(digitalocean) I need to add their nameserver to the domain. To point my client subdomain to the host(vercel) I also need to add their nameserver. I have done this. Is it a idea good to point multiple nameservers to one domain as i have done?
Also my server subdomain shows an ssl protocol error error after sometime then it goes back online. What might be the issue?
Is my configuration as stated above correct? if not which approach do you recommend?
In my case i bought a domain from dynadot and wanted to have several subdomains,one for the frontend and another for the backend. For frontend i hosted in vercel and for the server i was using digital ocean, and i had to setup digital oceans name servers in my domain host -dynadot so as to point my server subdomain to them. in doing that i could not set up a dns record or another nameserver in my domain host since i already have set up digital oceans nameserver already.What i was to do is to go digital ocean and add my vercel dns records from there.
