Creating a subdomain has error 503

I have created the main domain name, for example Then I want to create a subdomain in the same directory as the main domain (public_html). After creation, the subdomain got a 503 error.

Please help me. Thanks you!

Did u checked the dns configurations?

If not please include a Type A record for with the ip4 value

I have added DNS records for the subdomain. If you create a subdomain with another folder, it’s normal, but with the main domain’s folder, you get error 503.

Can u see it under subdomain list?

Do u have any logs?

I do see the subdomain in the list of subdomains.
