Thanks a lot for your prompt support. The 2 conflicting nameservers are old one that I configured on Namecheap before. The I changed those 2 to the 2 from Cloudflare.
In my Namecheap DNS congiuration I only have the 2 from Cloudflare.
If I check NS record I found:
If you’ve already applied for changes, kindly wait for propagation period. It could take some time. In the meantime, add A record to the Cloudflare DNS.
Thanks I will add the A record but I cannot see the two old nameservers when I do the NS record search. So It should be ok now i did the change 3 days ago.
Where are you retrieving the old nameservers?
Otherwise, if under Domain tab Nameservers → Custom DNS, are the assigned Cloudflare nameservers, you’re good to go and have to wait for a regular DNS propagation time as @neiljay stated. Might take up to 24-72 hours upon changes to apply them.
In Linux (even when checkiong for @1.1.1.1 or @8.8.8.8 DNS servers):
$ dig ns +trace myhomesite.eu
We get:
myhomesite.eu. 0 IN NS andronicus.ns.cloudflare.com.
myhomesite.eu. 0 IN NS brenda.ns.cloudflare.com.
But also see the old ones related to the TTL (time-to-live) cache at DNS:
myhomesite.eu. 86400 IN NS ns2.myhomesite.eu.
myhomesite.eu. 86400 IN NS brenda.ns.cloudflare.com.
myhomesite.eu. 86400 IN NS andronicus.ns.cloudflare.com.
myhomesite.eu. 86400 IN NS ns1.myhomesite.eu.

Online tool seems your Cloudflare nameservers are propagating:
