I am trying to setup a small Wordpress website, hosted on Vultr (Ubuntu w/ preinstalled Wordpress), having registered my domain name from Godaddy. What I usually do, when pointing to a hosting server, is I just change the A record on my DNS settings to point to my server IP, and it worked the first time. But we had some software issue with the server and decided to scrap it and spin up a new instance.
But this time I had a friend do the DNS remapping, who migrated all the default nameservers to Vultr nameservers, having deleted the original DNS records from Godaddy. But I somehow managed to switch back to the default Godaddy nameservers and have added an A record pointing to the server IP and a CNAME www record that points to my domain name (besides the default records that specify the 2 NS and the SOA record).
It has been 36 hours since I changed my domain nameservers to the default Godaddy NS but I keep getting
Temporary failure in name resolutionwhenever I try to ping it from my main workstation connected to my home network, even on different browsers.
I am having no issues pinging or opening the site using my mobile network. Even the customer service guys at Godaddy can view our website, but neither me nor my friend can open it.
I tried tracking the propagation at dnsmap.io and dnschecker and we keep getting unresolved at the same places as it were when we changed it back.
I am having a hard time figuring out what I am doing wrong, and I am asking for guidance. I am extremely sorry if this a noob question, but I am losing patience fast.
