Getting DNS_PROBE_FINISHED_NXDOMAIN on CNAME records

Hi
The domain playgorithm.net is owned by me via GoDaddy and managed via Cloudflare (I’ve set the CF nameservers in GoDaddy’s side).
I’ve setup couple of CNAME records in CF DNS management UI.
I’m getting DNS_PROBE_FINISHED_NXDOMAIN when I browse to those CNAMEs
for example:
files.playgorithm.net
backend1.playgorithm.net

How much time it takes to update?
It all worked well before, and the trouble started when the domain ownership was expired.
Since I renewed ownership it passed almost 3 days, but still I can’t access those URLs.
Any way to debug this?
Any help would be much appreciated!

They do resolve for me.

What’s the output of these commands?

nslookup files.playgorithm.net
nslookup backend1.playgorithm.net

nslookup files.playgorithm.net 1.1.1.1
nslookup backend1.playgorithm.net 1.1.1.1

nslookup files.playgorithm.net

Server: 192.168.140.9
Address: 192.168.140.9#53

** server can’t find files.playgorithm.net: NXDOMAIN

nslookup backend1.playgorithm.net

Server: 192.168.140.9
Address: 192.168.140.9#53

** server can’t find backend1.playgorithm.net: NXDOMAIN

That’s an issue with your local resolver. You said you set that up three days ago, right? In that case waiting probably wont change much and you will have to try to force it to update its cache.

What is the 1.1.1.1 argument?

The Cloudflare resolvers.

So if I pass 1.1.1.1 after the domain, it overrides my local dns resolver?

In the case of “nslookup”.

Again, you need to make sure your local resolver updates its cache. I presume “192.168.140.9” is your router, right? Maybe try to reboot it.

Thanks!
