Hello!

The CNAME record was added correctly and is available.:

dig +short NAME 123.metacampus.ru

egb16x5m.up.railway.applications.

This record may not be displayed in the service due to the fact that the service asks you to specify a CNAME record specifically for the domain. metacampus.ru .

However, a CNAME record can only be added for a subdomain.

On this issue, I recommend contacting the support service where the CNAME record value was requested.

Could you help me fast! Please!
I can't continue my work...(((
