Own nameserver not working

Hi, i installed and config sentora, im using digital ocean.

Im using a main domain, called: maindomain.com.br

In the digital ocean network panel, i insert the maindomain.com.br and config the records. In my registrar company i insert in the dns, MASTER: ns1.digitalocean.com and in the SLAVE: ns2.digitalocean.com

In the sentora panel, i create the domain: maindomain.com.br and create the dns configs and records.

The maindomain.com.br is working perfectly.

Now i create a second domain, called: seconddomain.com.br

First i create this seconddomain.com.br in sentora panel, and create the dns records. Then in the registrar company i create the seconddomain.com.br and in the dns configs i insert: MASTER: ns1.maindomain.com.br and SLAVE: ns2.maindomain.com.br, but when i save this dns config i get the error: UNKNOWN DNS.

Like the ns1.maindomain.com.br doesnt exist.

I already wait for 3 days and i get the same error.

Anyone can help me?

Im attaching my digital ocean dns config, and the maindomain.com.br and seconddomain.com.br in sentora config.

Thanks a lot!
