If you want to use the @ or www domain, you must add both records.

Some DNS providers don't support CNAME flattening (using CNAME records on root domain), so in that case, I'd try migrating to Cloudflare's DNS service and see if that helps.

Hi,

I updated the DNS configuration as requested.

Current DNS configuration:

CNAME

www → r871ylua.up.railway.app

TXT

_railway-verify.www → railway-verify=e4cca3b4a657e6f4ab09cf64154e...

DNS propagation is confirmed.

nslookup result:

www.sensi-collaboration.fr

→ r871ylua.up.railway.app

→ 151.101.66.15

Public DNS lookup tools also confirm the correct CNAME resolution.

However the Railway dashboard still shows:

“Waiting for DNS update”.

Could you please check if the domain verification cache might be stuck for this project?

Project: sensi-collaboration

Service: web

Thank you!

Hi,

I’ve now fully updated the DNS records to exactly match what Railway currently requests.

Current Railway requested records:

• CNAME: www → r871ylua.up.railway.app
• TXT: _railway-verify.www → railway-verify=e4cca3b4a657e6f4ab09cf64154e...

Current DNS at IONOS matches exactly:

• CNAME: www → r871ylua.up.railway.app
• TXT: _railway-verify.www → railway-verify=e4cca3b4a657e6f4ab09cf64154e...

Propagation is confirmed externally.

nslookup www.sensi-collaboration.fr returns:

• canonical name: r871ylua.up.railway.app
• address: 151.101.66.15

Public DNS lookup tools also confirm the same CNAME resolution.

However, Railway still shows:

“Waiting for DNS update”

Since the DNS now exactly matches Railway’s requested records and propagation is confirmed, could you please manually check or clear the domain verification cache for this project / service?

Project: sensi-collaboration

Service: web

Domain: www.sensi-collaboration.fr

Thank you.

For further information, currently I have => "railway-verify=e4cca3b4a657e6f4ab09cf64154e..."

PS C:\Users\guibs\Documents\global\public> nslookup www.sensi-collaboration.fr

Again, as mentioned above, if you wish to use www, you'll also need to add @ records to your DNS provider.

Some DNS providers don't support CNAME flattening (using CNAME records on root domain), so in that case, I'd try migrating to Cloudflare's DNS service and see if that helps.

@ OP

Add root and www. Cname flatten - try Cloudflare if your host (like godaddy) wont allow cname on the root.

Hi,

Just to clarify: I only intend to use the www subdomain, not the root domain.

Current DNS configuration:

CNAME

www → r871ylua.up.railway.app

TXT

_railway-verify.www → railway-verify=e4cca3b4a657e6f4ab09cf64154e...

DNS propagation is confirmed:

nslookup www.sensi-collaboration.fr

→ r871ylua.up.railway.app

→ 151.101.66.15

External DNS lookup tools confirm the same.

Since the DNS configuration matches exactly what Railway expects, could a staff member please check if the domain verification for this project might be stuck?

Thank you.

and I have => Thank you.

LOL, yes bro, but domain.com must resolve to somewhere first, then domain.com can tell the world to 307 to www.domain.com

Try make domain.com online with A-record first.

Hi there, all is fine for now, thank you for your help ! 🙂

Guillaume.

Glad to hear it's working now! Marking this as solved.
