I am trying to use my custom domain and when configuring the DNS records (type: CNAME, Name: @), Godaddy does not allow it. After searching for a solution I found that the problem is due to a fundamental DNS limitation: CNAME records cannot exist at the root domain level (using @) according to RFC standards. Any suggestion?

Hey @manic urchin, please change your domain's nameservers to Cloudflare's and let Cloudflare handle it, as they support CNAME flattening.

Am I allowed to do so even if the domain was purchased through godaddy?
@spiral flint
spiral flint
Yes, while I haven't used Godaddy myself, I have successfully guided other users with the same problem.
spiral flint
It could be added as a warning
Do you mean like a warning in the UI for when someone attempts to add a root domain with an incompatible DNS provider such as Godaddy?
manic urchin
yes
manic urchin
Done, thank you
manic urchin
An A, AAAA, or CNAME record with that host already exists. For more details, refer to https://developers.cloudflare.com/dns/manage-dns-records/troubleshooting/records-with-same-name/.
@spiral flint This is the error I am receving when adding a CNAME @ record
Any suggestion?
Current records
easylanguagecoder.com is the domain
spiral flint
Please delete the A records in this case
manic urchin
Please explain why
spiral flint
Because they are conflicting as per the error you just mentioned
manic urchin
Deleting both of them?
spiral flint
Yes
manic urchin
They were copied from godaddy I guess. What do you think they were pointing to?
Trying to get my head around it
CNAME was added successfully
Hence only these two records are enough?

I suppose that it is for showing their own parking page.

yes
manic urchin
Thank you. I guess I have to wait for them to propagate
spiral flint
please set the Cloudflare SSL/TLS settings to Full https://docs.railway.com/guides/public-networking#provider-specific-instructions
spiral flint
No, it has to be Full and not Full (strict)
manic urchin
Modified, thank you
spiral flint
Can you confirm that your application is now reachable?
spiral flint
You can try it if you want to, but it looks like that everything is configured correctly, as I can access it via Google's DNS servers.
manic urchin
Ok thank you I receive the error 400 as well
spiral flint
Ok thank you I receive the error 400 as well
Interesting, did you add the domain before changing your nameservers to Cloudflare's?
spiral flint
Did you also add the CNAME record again?
spiral flint
Hey, can you try accessing https://easylanguagecoder.com/ again now?
manic urchin
Hey, can you try accessing https://easylanguagecoder.com/ again now?
Yes that was my fault and had to add the new domain to the project's settings
manic urchin
"record not yet detected"
Sorry for all the messages but shouldnt https://www.easylanguagecoder.com/ be working as well?
spiral flint
You didn't add the www subdomain or create a redirect rule in Cloudflare.
manic urchin
Doesnt the second record take care of that?
spiral flint
No, you will have to add it too
manic urchin
ok thank you. Last question, should the railway ui message update itself or is it a bug?
spiral flint
It will be updated, however this may take some time
manic urchin
Appreciate your help, Any way I can leave a positive review for the support you gave?
spiral flint
I am not aware of a way to leave a review via Discord, you may try https://station.railway.com/questions/custom-domain-6e3f2fac if you really wish to.
In any case, I'll mark this thread as solved for now. 🙂
