Hey there! We've found the following might help you get unblocked faster:

• 🧵 can't setup domain

• 🧵 Custom domain setup

• 🧵 Custom Domain set up at both (@) and (www) but only www is working (Cloudflare)

If you find the answer from one of these, please let us know by solving the thread!

Hi, if you cant add @ hostname, you should connect your dns to cloudflare. Cloudflare allows @ and other setup to work, and it seemless with railway.

The One.com Solution: Leave the Hostname Field Blank

According to One.com's official documentation, to create a record for your root domain (yourdomain.com), you must leave the hostname field completely empty. An empty hostname field in their system is the direct equivalent of using @ elsewhere.

Why this works: In DNS, the @ symbol is a placeholder that represents the root domain itself. One.com's system is designed to interpret a blank hostname as this @ record.

To Verify It's Working

1. Wait for propagation. DNS changes can take from 5 minutes to 48 hours to take effect globally. It is often faster, but please be patient.

2. Use a DNS lookup tool. After at least 30 minutes, go to a site like DNS Checker.

   • Select the record type you created.

   • Type your domain name into the search bar (e.g., yourdomain.com) and run the check.

   • If the change is successful, the tool will show the new value you set propagating across servers around the world.
