I'd recommend migrating to Cloudflare's DNS.

cname cant exist at a domains root, thats a dns rule not a godaddy or railway bug, its because the root also needs SOA/NS records too

you can read it here : https://betterstack.com/community/questions/why-cant-cname-be-used-at-the-root-of-domain/

if you dont wanna switch dns providers: point www to railway with a cname, then use godaddy's domain forwarding to redirect your bare domain to www with a 301. only catch is the url bar will show www.yourdomain.com when someone visits the root

can u tell me how

You'd add the domain as www.<YOUR_DOMAIN> in Railway instead of just your domain.

You'd then create a forwarding rule in your dashboard.

Although I'd recommend migrating to Cloudflare's DNS, as they also provide a vast amount of other features that may become useful.

if you feel its kinda complicated i think you can follow the mod advise switching to cloudflare DNS

now i made it and it worked on go daddy but now it still when i type www. it still dont work

Can you define "still doesn't work"?

can you share a screenshot that will make us understand better what you trying to explain

did you also add www.yourdomain.com as a custom domain inside railway itself (service settings → networking → domains)? the godaddy cname only handles dns, railway still needs to know that hostname belongs to your service or it'll reject the request even if dns is pointing correctly

Did you add the CNAME and TXT record to Godaddy?

Yes i did

Yes i did this

Can you show a screenshot of your DNS page?

I wasn't able to find any DNS records associated with the domain you're using.

I'd check if your domain was typed correctly. I'm not able to find anything on el-banna.store, let alone www.el-banna.store.

check inside railway and see if its correspond

They are the same in both

try to copy and paste from godaddy direct to railway dont type it manually

also check the mod is saying they cant find any dns records of the doman re-verify
