Just to let you know again that this issue happened on our old domain which just turned DNS_PROBE_FINISHED_NXDOMAIN by itself
so we have the domain arcellatelecom.com and is added to Cloudflare with everything working correctly, but yesterday we had the error DNS_PROBE_FINISHED_NXDOMAIN out of the blue, nothing changed in the domain nor Cloudflare configuration.
We have servers located in Germany and we tried to access the website from there and it works without any issue, but locally here in Iraq all our
nslookup attempts failed.

and here is our server response
EDIT: Server response was due to cached DNS record, nslookup failed locating our dmain
