I have attached pictures for added strength.

Can you tell me where is your domain hosted?

Registered at cloudflare.com

CNAME points to misterios-production.up.railway.app

Hello,

That would be the incorrect configuration, please remove the domain from Railway, and remove your DNS settings from your DNS config, then add the domain back to Railway and be sure to set the given CNAME correctly in your DNS settings.

Hi! I didn't think that I had to delete and add again.

Did you know that cloudflare doesn't allow adding a CNAME record @ zy25qkto.up.railway.app ?

I added CNAME * zy25qkto.up.railway.app and it seems to work

Cloudflare does allow adding a CNAME at the root with @, I've set it up many dozens of times that way, and recommended it many hundreds of times.

Please use @ at the root instead of * to avoid any potential issues down the line.

I understand how important it is to comply with technical requirements, but I have attached pictures with errors.

Please read the error, you need to remove any other root level DNS settings before you can set the proper value.

Indeed, deletes all records managed to add @ with the desired inscription. Thank you for your patience and have a nice day.

No problem! you have a nice day / night as well!
