Nameservers are listed as invalid despite it showing the same in the “delete your current Nameservers” section. The current ones show up as having a . at the end, but I can’t remove that as it doesn’t appear on the registrar site.
Nameservers
Just to add, I have 2 other domains with the same registrar that are working fine with cloudflare and their NS were changed at the same time
The trailing dot is normal DNS notation and not the actual problem. Here’s what’s going on:
In DNS, a trailing dot (e.g., lilith.ns.cloudflare.com``.) simply means it’s a fully qualified domain name (FQDN) — it points to the root of the DNS hierarchy. It’s standard, correct syntax. You don’t need to remove it, and it’s not causing the “invalid” status.
Cloudflare marks nameservers as “invalid” when what it detects at the registrar doesn’t match what it assigned to your zone. The most common reasons:
Cloudflare assigns a specific pair of nameservers to each zone. Since your other 2 domains work fine with the same registrar, you might have accidentally set the nameservers from one of those other domains on this one. Each domain gets its own unique pair — you can’t reuse them.
Double-check that the nameservers shown on this domain’s Cloudflare dashboard page match exactly what’s set at the registrar.
Some registrars keep old nameservers alongside new ones instead of replacing them. Cloudflare requires only its assigned pair — no extras. Verify at your registrar that there are exactly 2 nameservers and no others.
If this domain was ever added to a different Cloudflare account (even briefly), that old zone’s nameserver assignment may still be active. The fix is to remove the domain from the old account.
You can check what the internet currently sees vs. what Cloudflare expects:
# What the world sees
dig yourdomain.com NS @8.8.8.8
# Compare with what Cloudflare's dashboard shows for this zone
If the results don’t match Cloudflare’s assigned pair for this specific domain, the registrar hasn’t propagated correctly yet or the wrong nameservers are set.
| Symptom | Likely Cause | Fix |
|---|---|---|
| Trailing dot on NS | Normal DNS FQDN notation | Ignore it |
| “Invalid” status | NS mismatch | Set only the exact pair Cloudflare assigned to this zone |
| Other domains work fine | Different zones get different NS pairs | Don’t copy nameservers from other domains |
Happy to be of help
