Question

DNS Not Resolving to IP

Posted November 21, 2020 471 views
NginxDNS

Hello, I have a Docker droplet set up with a .NET Blazor app. I can access the app through the IP address no problem.

My domain is registered through Google Domains, and three days ago I changed the DNS servers to DigitalOcean. I turned off DNSSEC, waited two days, then entered the Digital Ocean name servers. Three days later and my domain is still not resolving.

On the Digital Ocean side, I have an A record at the root which directs to my droplet IP address. I have three NS entries at the root which direct to the three Digital Ocean name servers.

nslookup mysite.com returns the IP address of my droplet. I have tried clearing the local DNS cache on both my machines.

Is there something I could be missing?

Thanks!

Hi there @jghtch,

It does not sound like an issue with the DNS, as when running nslookup you get your IP address back, which means that the DNS is configured correctly.

I could suggest trying out this tool to see if you also get back the correct IP address as your A record:

https://www.digitalocean.com/community/tools/dns

Lately, I’ve noticed that some browsers like Chrome redirect http:// to https:// by default, and if you don’t have SSL installed on your server, the connection will time out. You could try accessing your domain via http:// directly and see if it loads.

If this is the case, I could suggest installing an SSL certificate so that your domain could work with both http:// and https://. You can use Let’s Encrypt as a free SSL certificate provider.

I hope that this helps!
Regards,
Bobby

Hi @bobbyiliev thanks for the reply.

I do get my IP back using the Digital Ocean DNS tool you linked.

I don’t believe I have SSL installed on my server yet, so that could be part of the problem. The site doesn’t load over http however.
